fix: remove mcp-types from app server protocol (#4537 )

We continue the separation between `codex app-server` and `codex
mcp-server`.

In particular, we introduce a new crate, `codex-app-server-protocol`,
and migrate `codex-rs/protocol/src/mcp_protocol.rs` into it, renaming it
`codex-rs/app-server-protocol/src/protocol.rs`.

Because `ConversationId` was defined in `mcp_protocol.rs`, we move it
into its own file, `codex-rs/protocol/src/conversation_id.rs`, and
because it is referenced in a ton of places, we have to touch a lot of
files as part of this PR.

We also decide to get away from proper JSON-RPC 2.0 semantics, so we
also introduce `codex-rs/app-server-protocol/src/jsonrpc_lite.rs`, which
is basically the same `JSONRPCMessage` type defined in `mcp-types`
except with all of the `"jsonrpc": "2.0"` removed.

Getting rid of `"jsonrpc": "2.0"` makes our serialization logic
considerably simpler, as we can lean heavier on serde to serialize
directly into the wire format that we use now.

OpenTelemetry events (#2103 )

### Title

## otel

Codex can emit [OpenTelemetry](https://opentelemetry.io/) **log events**
that
describe each run: outbound API requests, streamed responses, user
input,
tool-approval decisions, and the result of every tool invocation. Export
is
**disabled by default** so local runs remain self-contained. Opt in by
adding an
`[otel]` table and choosing an exporter.

```toml
[otel]
environment = "staging"   # defaults to "dev"
exporter = "none"          # defaults to "none"; set to otlp-http or otlp-grpc to send events
log_user_prompt = false    # defaults to false; redact prompt text unless explicitly enabled
```

Codex tags every exported event with `service.name = "codex-cli"`, the
CLI
version, and an `env` attribute so downstream collectors can distinguish
dev/staging/prod traffic. Only telemetry produced inside the
`codex_otel`
crate—the events listed below—is forwarded to the exporter.

### Event catalog

Every event shares a common set of metadata fields: `event.timestamp`,
`conversation.id`, `app.version`, `auth_mode` (when available),
`user.account_id` (when available), `terminal.type`, `model`, and
`slug`.

With OTEL enabled Codex emits the following event types (in addition to
the
metadata above):

- `codex.api_request`
  - `cf_ray` (optional)
  - `attempt`
  - `duration_ms`
  - `http.response.status_code` (optional)
  - `error.message` (failures)
- `codex.sse_event`
  - `event.kind`
  - `duration_ms`
  - `error.message` (failures)
  - `input_token_count` (completion only)
  - `output_token_count` (completion only)
  - `cached_token_count` (completion only, optional)
  - `reasoning_token_count` (completion only, optional)
  - `tool_token_count` (completion only)
- `codex.user_prompt`
  - `prompt_length`
  - `prompt` (redacted unless `log_user_prompt = true`)
- `codex.tool_decision`
  - `tool_name`
  - `call_id`
- `decision` (`approved`, `approved_for_session`, `denied`, or `abort`)
  - `source` (`config` or `user`)
- `codex.tool_result`
  - `tool_name`
  - `call_id`
  - `arguments`
  - `duration_ms` (execution time for the tool)
  - `success` (`"true"` or `"false"`)
  - `output`

### Choosing an exporter

Set `otel.exporter` to control where events go:

- `none` – leaves instrumentation active but skips exporting. This is
the
  default.
- `otlp-http` – posts OTLP log records to an OTLP/HTTP collector.
Specify the
  endpoint, protocol, and headers your collector expects:

  ```toml
  [otel]
  exporter = { otlp-http = {
    endpoint = "https://otel.example.com/v1/logs",
    protocol = "binary",
    headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" }
  }}
  ```

- `otlp-grpc` – streams OTLP log records over gRPC. Provide the endpoint
and any
  metadata headers:

  ```toml
  [otel]
  exporter = { otlp-grpc = {
    endpoint = "https://otel.example.com:4317",
    headers = { "x-otlp-meta" = "abc123" }
  }}
  ```

If the exporter is `none` nothing is written anywhere; otherwise you
must run or point to your
own collector. All exporters run on a background batch worker that is
flushed on
shutdown.

If you build Codex from source the OTEL crate is still behind an `otel`
feature
flag; the official prebuilt binaries ship with the feature enabled. When
the
feature is disabled the telemetry hooks become no-ops so the CLI
continues to
function without the extra dependencies.

update composer + user message styling (#4240 )

Changes:

- the composer and user messages now have a colored background that
stretches the entire width of the terminal.
- the prompt character was changed from a cyan `▌` to a bold `›`.
- the "working" shimmer now follows the "dark gray" color of the
terminal, better matching the terminal's color scheme

chore: remove once_cell dependency from multiple crates (#4154 )

This commit removes the `once_cell` dependency from `Cargo.toml` files
in the `codex-rs` and `apply-patch` directories, replacing its usage
with `std::sync::LazyLock` and `std::sync::OnceLock` where applicable.
This change simplifies the dependency tree and utilizes standard library
features for lazy initialization.

feat: git tooling for undo (#3914 )

## Summary
Introduces a “ghost commit” workflow that snapshots the tree without
touching refs.
1. git commit-tree writes an unreferenced commit object from the current
index, optionally pointing to the current HEAD as its parent.
2. We then stash that commit id and use git restore --source <ghost> to
roll the worktree (and index) back to the recorded snapshot later on.

## Details
- Ghost commits live only as loose objects—we never update branches or
tags—so the repo history stays untouched while still giving us a full
tree snapshot.
- Force-included paths let us stage otherwise ignored files before
capturing the tree.
- Restoration rehydrates both tracked and force-included files while
leaving untracked/ignored files alone.

chore(deps): bump tracing-subscriber from 0.3.19 to 0.3.20 in /codex-rs (#3620 )

Bumps [tracing-subscriber](https://github.com/tokio-rs/tracing) from
0.3.19 to 0.3.20.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/tokio-rs/tracing/releases">tracing-subscriber's
releases</a>.</em></p>
<blockquote>
<h2>tracing-subscriber 0.3.20</h2>
<p><strong>Security Fix</strong>: ANSI Escape Sequence Injection
(CVE-TBD)</p>
<h2>Impact</h2>
<p>Previous versions of tracing-subscriber were vulnerable to ANSI
escape sequence injection attacks. Untrusted user input containing ANSI
escape sequences could be injected into terminal output when logged,
potentially allowing attackers to:</p>
<ul>
<li>Manipulate terminal title bars</li>
<li>Clear screens or modify terminal display</li>
<li>Potentially mislead users through terminal manipulation</li>
</ul>
<p>In isolation, impact is minimal, however security issues have been
found in terminal emulators that enabled an attacker to use ANSI escape
sequences via logs to exploit vulnerabilities in the terminal
emulator.</p>
<h2>Solution</h2>
<p>Version 0.3.20 fixes this vulnerability by escaping ANSI control
characters in when writing events to destinations that may be printed to
the terminal.</p>
<h2>Affected Versions</h2>
<p>All versions of tracing-subscriber prior to 0.3.20 are affected by
this vulnerability.</p>
<h2>Recommendations</h2>
<p>Immediate Action Required: We recommend upgrading to
tracing-subscriber 0.3.20 immediately, especially if your
application:</p>
<ul>
<li>Logs user-provided input (form data, HTTP headers, query parameters,
etc.)</li>
<li>Runs in environments where terminal output is displayed to
users</li>
</ul>
<h2>Migration</h2>
<p>This is a patch release with no breaking API changes. Simply update
your Cargo.toml:</p>
<pre lang="toml"><code>[dependencies]
tracing-subscriber = &quot;0.3.20&quot;
</code></pre>
<h2>Acknowledgments</h2>
<p>We would like to thank <a href="http://github.com/zefr0x">zefr0x</a>
who responsibly reported the issue at
<code>security@tokio.rs</code>.</p>
<p>If you believe you have found a security vulnerability in any
tokio-rs project, please email us at <code>security@tokio.rs</code>.</p>

feat: add Android/Termux support by gating arboard dependency (#2895 )

## Summary

This PR enables Codex to build and run on Android/Termux environments by
conditionally gating the arboard clipboard dependency for Android
targets.

## Key Changes

- **Android Compatibility**: Gate arboard dependency for Android targets
where clipboard access may be restricted
- **Build Fixes**: Add missing tempfile::Builder import for image
clipboard operations
- **Code Cleanup**: Remove unnecessary parentheses to resolve formatting
warnings

## Technical Details

### Clipboard Dependency Gating
- Uses conditional compilation to exclude arboard on Android targets
- Maintains full clipboard functionality on other platforms
- Prevents build failures on Android/Termux where system clipboard
access is limited

### Import Fixes
- Adds missing tempfile::Builder import that was causing compilation
errors
- Ensures image clipboard operations work correctly when clipboard is
available

## Platform Support

- ✅ **Linux/macOS/Windows**: Full clipboard functionality maintained
- ✅ **Android/Termux**: Builds successfully without clipboard dependency
- ✅ **Other Unix platforms**: Unchanged behavior

## Testing

- ✅ Builds successfully on Android/Termux
- ✅ Maintains clipboard functionality on supported platforms  
- ✅ No regression in existing functionality

This addresses the Android/Termux compatibility issues while keeping
clipboard functionality intact for platforms that support it.

Copying / Dragging image files (MacOS Terminal + iTerm) (#2567 )

In this PR:

- [x] Add support for dragging / copying image files into chat.
- [x] Don't remove image placeholders when submitting.
- [x] Add tests.

Works for:

- Image Files
- Dragging MacOS Screenshots (Terminal, iTerm)

Todos:

- [ ] In some terminals (VSCode, WIndows Powershell, and remote
SSH-ing), copy-pasting a file streams the escaped filepath as individual
key events rather than a single Paste event. We'll need to have a
function (in a separate PR) for detecting these paste events.

one?

refactor onboarding screen to a separate "app" (#2524 )

this is in preparation for adding more separate "modes" to the tui, in
particular, a "transcript mode" to view a full history once #2316 lands.

1. split apart "tui events" from "app events".
2. remove onboarding-related events from AppEvent.
3. move several general drawing tools out of App and into a new Tui
class

Introduce --oss flag to use gpt-oss models (#1848 )

This adds support for easily running Codex backed by a local Ollama
instance running our new open source models. See
https://github.com/openai/gpt-oss for details.

If you pass in `--oss` you'll be prompted to install/launch ollama, and
it will automatically download the 20b model and attempt to use it.

We'll likely want to expand this with some options later to make the
experience smoother for users who can't run the 20b or want to run the
120b.

custom textarea (#1794 )

This replaces tui-textarea with a custom textarea component.

Key differences:
1. wrapped lines
2. better unicode handling
3. uses the native terminal cursor

This should perhaps be spun out into its own separate crate at some
point, but for now it's convenient to have it in-tree.

check for updates (#1764 )

1. Ping https://api.github.com/repos/openai/codex/releases/latest (at
most once every 20 hrs)
2. Store the result in ~/.codex/version.jsonl
3. If CARGO_PKG_VERSION < latest_version, print a message at boot.

Detect kitty terminals (#1748 )

We want to detect kitty terminals so we can preferentially upgrade their UX without degrading older terminals.

fix: correctly wrap history items (#1685 )

The overall idea here is: skip ratatui for writing into scrollback,
because its primitives are wrong. We want to render full lines of text,
that will be wrapped natively by the terminal, and which we never plan
to update using ratatui (so the `Buffer` struct is overhead and in fact
an inhibition).

Instead, we use ANSI scrolling regions (link reference doc to come).
Essentially, we:
1. Define a scrolling region that extends from the top of the prompt
area all the way to the top of scrollback
2. Scroll that region up by N < (screen_height - viewport_height) lines,
in this PR N=1
3. Put our cursor at the top of the newly empty region
4. Print out our new text like normal

The terminal interactions here (write_spans and its dependencies) are
mostly extracted from ratatui.

Easily Selectable History (#1672 )

This update replaces the previous ratatui history widget with an
append-only log so that the terminal can handle text selection and
scrolling. It also disables streaming responses, which we'll do our best
to bring back in a later PR. It also adds a small summary of token use
after the TUI exits.

Add paste summarization to Codex TUI (#1549 )

## Summary
- introduce `Paste` event to avoid per-character paste handling
- collapse large pasted blocks to `[Pasted Content X lines]`
- store the real text so submission still includes it
- wire paste handling through `App`, `ChatWidget`, `BottomPane`, and
`ChatComposer`

## Testing
- `cargo test -p codex-tui`

feat: add support for @ to do file search (#1401 )

Introduces support for `@` to trigger a fuzzy-filename search in the
composer. Under the hood, this leverages
https://crates.io/crates/nucleo-matcher to do the fuzzy matching and
https://crates.io/crates/ignore to build up the list of file candidates
(so that it respects `.gitignore`).

For simplicity (at least for now), we do not do any caching between
searches like VS Code does for its file search:

https://github.com/microsoft/vscode/blob/1d89ed699b2e924d418c856318a3e12bca67ff3a/src/vs/workbench/services/search/node/rawSearchService.ts#L212-L218

Because we do not do any caching, I saw queries take up to three seconds
on large repositories with hundreds of thousands of files. To that end,
we do not perform searches synchronously on each keystroke, but instead
dispatch an event to do the search on a background thread that
asynchronously reports back to the UI when the results are available.
This is largely handled by the `FileSearchManager` introduced in this
PR, which also has logic for debouncing requests so there is at most one
search in flight at a time.

While we could potentially polish and tune this feature further, it may
already be overengineered for how it will be used, in practice, so we
can improve things going forward if it turns out that this is not "good
enough" in the wild.

Note this feature does not work like `@` in the TypeScript CLI, which
was more like directory-based tab completion. In the Rust CLI, `@`
triggers a full-repo fuzzy-filename search.

Fixes https://github.com/openai/codex/issues/1261.

`codex exec`) to summarize the sandbox config.

feat: add support for login with ChatGPT (#1212 )

This does not implement the full Login with ChatGPT experience, but it
should unblock people.

**What works**

* The `codex` multitool now has a `login` subcommand, so you can run
`codex login`, which should write `CODEX_HOME/auth.json` if you complete
the flow successfully. The TUI will now read the `OPENAI_API_KEY` from
`auth.json`.
* The TUI should refresh the token if it has expired and the necessary
information is in `auth.json`.
* There is a `LoginScreen` in the TUI that tells you to run `codex
login` if both (1) your model provider expects to use `OPENAI_API_KEY`
as its env var, and (2) `OPENAI_API_KEY` is not set.

**What does not work**

* The `LoginScreen` does not support the login flow from within the TUI.
Instead, it tells you to quit, run `codex login`, and then run `codex`
again.
* `codex exec` does read from `auth.json` yet, nor does it direct the
user to go through the login flow if `OPENAI_API_KEY` is not be found.
* The `maybeRedeemCredits()` function from `get-api-key.tsx` has not
been ported from TypeScript to `login_with_chatgpt.py` yet:


https://github.com/openai/codex/blob/a67a67f3258fc21e147b6786a143fe3e15e6d5ba/codex-cli/src/utils/get-api-key.tsx#L84-L89

**Implementation**

Currently, the OAuth flow requires running a local webserver on
`127.0.0.1:1455`. It seemed wasteful to incur the additional binary cost
of a webserver dependency in the Rust CLI just to support login, so
instead we implement this logic in Python, as Python has a `http.server`
module as part of its standard library. Specifically, we bundle the
contents of a single Python file as a string in the Rust CLI and then
use it to spawn a subprocess as `python3 -c
{{SOURCE_FOR_PYTHON_SERVER}}`.

As such, the most significant files in this PR are:

```
codex-rs/login/src/login_with_chatgpt.py
codex-rs/login/src/lib.rs
```

Now that the CLI may load `OPENAI_API_KEY` from the environment _or_
`CODEX_HOME/auth.json`, we need a new abstraction for reading/writing
this variable, so we introduce:

```
codex-rs/core/src/openai_api_key.rs
```

Note that `std::env::set_var()` is [rightfully] `unsafe` in Rust 2024,
so we use a LazyLock<RwLock<Option<String>>> to store `OPENAI_API_KEY`
so it is read in a thread-safe manner.

Ultimately, it should be possible to go through the entire login flow
from the TUI. This PR introduces a placeholder `LoginScreen` UI for that
right now, though the new `codex login` subcommand introduced in this PR
should be a viable workaround until the UI is ready.

**Testing**

Because the login flow is currently implemented in a standalone Python
file, you can test it without building any Rust code as follows:

```
rm -rf /tmp/codex_home && mkdir /tmp/codex_home
CODEX_HOME=/tmp/codex_home python3 codex-rs/login/src/login_with_chatgpt.py
```

For reference:

* the original TypeScript implementation was introduced in
https://github.com/openai/codex/pull/963
* support for redeeming credits was later added in
https://github.com/openai/codex/pull/974

codex-rs: make tool calls prettier (#1211 )

This PR overhauls how active tool calls and completed tool calls are
displayed:

1. More use of colour to indicate success/failure and distinguish
between components like tool name+arguments
2. Previously, the entire `CallToolResult` was serialized to JSON and
pretty-printed. Now, we extract each individual `CallToolResultContent`
and print those
1. The previous solution was wasting space by unnecessarily showing
details of the `CallToolResult` struct to users, without formatting the
actual tool call results nicely
2. We're now able to show users more information from tool results in
less space, with nicer formatting when tools return JSON results

### Before:

<img width="1251" alt="Screenshot 2025-06-03 at 11 24 26"
src="https://github.com/user-attachments/assets/5a58f222-219c-4c53-ace7-d887194e30cf"
/>

### After:

<img width="1265" alt="image"
src="https://github.com/user-attachments/assets/99fe54d0-9ebe-406a-855b-7aa529b91274"
/>

## Future Work

1. Integrate image tool result handling better. We should be able to
display images even if they're not the first `CallToolResultContent`
2. Users should have some way to view the full version of truncated tool
results
3. It would be nice to add some left padding for tool results, make it
more clear that they are results. This is doable, just a little fiddly
due to the way `first_visible_line` scrolling works
4. There's almost certainly a better way to format JSON than "all on 1
line with spaces to make Ratatui wrapping work". But I think that works
OK for now.

fix: introduce ResponseInputItem::McpToolCallOutput variant (#1151 )

The output of an MCP server tool call can be one of several types, but
to date, we treated all outputs as text by showing the serialized JSON
as the "tool output" in Codex:


https://github.com/openai/codex/blob/25a9949c49194d5a64de54a11bcc5b4724ac9bd5/codex-rs/mcp-types/src/lib.rs#L96-L101

This PR adds support for the `ImageContent` variant so we can now
display an image output from an MCP tool call.

In making this change, we introduce a new
`ResponseInputItem::McpToolCallOutput` variant so that we can work with
the `mcp_types::CallToolResult` directly when the function call is made
to an MCP server.

Though arguably the more significant change is the introduction of
`HistoryCell::CompletedMcpToolCallWithImageOutput`, which is a cell that
uses `ratatui_image` to render an image into the terminal. To support
this, we introduce `ImageRenderCache`, cache a
`ratatui_image::picker::Picker`, and `ensure_image_cache()` to cache the
appropriate scaled image data and dimensions based on the current
terminal size.

To test, I created a minimal `package.json`:

```json
{
  "name": "kitty-mcp",
  "version": "1.0.0",
  "type": "module",
  "description": "MCP that returns image of kitty",
  "main": "index.js",
  "dependencies": {
    "@modelcontextprotocol/sdk": "^1.12.0"
  }
}
```

with the following `index.js` to define the MCP server:

```js
#!/usr/bin/env node

import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { readFile } from "node:fs/promises";
import { join } from "node:path";

const IMAGE_URI = "image://Ada.png";

const server = new McpServer({
  name: "Demo",
  version: "1.0.0",
});

server.tool(
  "get-cat-image",
  "If you need a cat image, this tool will provide one.",
  async () => ({
    content: [
      { type: "image", data: await getAdaPngBase64(), mimeType: "image/png" },
    ],
  })
);

server.resource("Ada the Cat", IMAGE_URI, async (uri) => {
  const base64Image = await getAdaPngBase64();
  return {
    contents: [
      {
        uri: uri.href,
        mimeType: "image/png",
        blob: base64Image,
      },
    ],
  };
});

async function getAdaPngBase64() {
  const __dirname = new URL(".", import.meta.url).pathname;
  // From https://github.com/benjajaja/ratatui-image/blob/9705ce2c59ec669abbce2924cbfd1f5ae22c9860/assets/Ada.png
  const filePath = join(__dirname, "Ada.png");
  const imageData = await readFile(filePath);
  const base64Image = imageData.toString("base64");
  return base64Image;
}

const transport = new StdioServerTransport();
await server.connect(transport);
```

With the local changes from this PR, I added the following to my
`config.toml`:

```toml
[mcp_servers.kitty]
command = "node"
args = ["/Users/mbolin/code/kitty-mcp/index.js"]
```

Running the TUI from source:

```
cargo run --bin codex -- --model o3 'I need a picture of a cat'
```

I get:

<img width="732" alt="image"
src="https://github.com/user-attachments/assets/bf80b721-9ca0-4d81-aec7-77d6899e2869"
/>

Now, that said, I have only tested in iTerm and there is definitely some
funny business with getting an accurate character-to-pixel ratio
(sometimes the `CompletedMcpToolCallWithImageOutput` thinks it needs 10
rows to render instead of 4), so there is still work to be done here.

fix: overhaul how we spawn commands under seccomp/landlock on Linux (#1086 )

Historically, we spawned the Seatbelt and Landlock sandboxes in
substantially different ways:

For **Seatbelt**, we would run `/usr/bin/sandbox-exec` with our policy
specified as an arg followed by the original command:


https://github.com/openai/codex/blob/d1de7bb383552e8fadd94be79d65d188e00fd562/codex-rs/core/src/exec.rs#L147-L219

For **Landlock/Seccomp**, we would do
`tokio::runtime::Builder::new_current_thread()`, _invoke
Landlock/Seccomp APIs to modify the permissions of that new thread_, and
then spawn the command:


https://github.com/openai/codex/blob/d1de7bb383552e8fadd94be79d65d188e00fd562/codex-rs/core/src/exec_linux.rs#L28-L49

While it is neat that Landlock/Seccomp supports applying a policy to
only one thread without having to apply it to the entire process, it
requires us to maintain two different codepaths and is a bit harder to
reason about. The tipping point was
https://github.com/openai/codex/pull/1061, in which we had to start
building up the `env` in an unexpected way for the existing
Landlock/Seccomp approach to continue to work.

This PR overhauls things so that we do similar things for Mac and Linux.
It turned out that we were already building our own "helper binary"
comparable to Mac's `sandbox-exec` as part of the `cli` crate:


https://github.com/openai/codex/blob/d1de7bb383552e8fadd94be79d65d188e00fd562/codex-rs/cli/Cargo.toml#L10-L12

We originally created this to build a small binary to include with the
Node.js version of the Codex CLI to provide support for Linux
sandboxing.

Though the sticky bit is that, at this point, we still want to deploy
the Rust version of Codex as a single, standalone binary rather than a
CLI and a supporting sandboxing binary. To satisfy this goal, we use
"the arg0 trick," in which we:

* use `std::env::current_exe()` to get the path to the CLI that is
currently running
* use the CLI as the `program` for the `Command`
* set `"codex-linux-sandbox"` as arg0 for the `Command`

A CLI that supports sandboxing should check arg0 at the start of the
program. If it is `"codex-linux-sandbox"`, it must invoke
`codex_linux_sandbox::run_main()`, which runs the CLI as if it were
`codex-linux-sandbox`. When acting as `codex-linux-sandbox`, we make the
appropriate Landlock/Seccomp API calls and then use `execvp(3)` to spawn
the original command, so do _replace_ the process rather than spawn a
subprocess. Incidentally, we do this before starting the Tokio runtime,
so the process should only have one thread when `execvp(3)` is called.

Because the `core` crate that needs to spawn the Linux sandboxing is not
a CLI in its own right, this means that every CLI that includes `core`
and relies on this behavior has to (1) implement it and (2) provide the
path to the sandboxing executable. While the path is almost always
`std::env::current_exe()`, we needed to make this configurable for
integration tests, so `Config` now has a `codex_linux_sandbox_exe:
Option<PathBuf>` property to facilitate threading this through,
introduced in https://github.com/openai/codex/pull/1089.

This common pattern is now captured in
`codex_linux_sandbox::run_with_sandbox()` and all of the `main.rs`
functions that should use it have been updated as part of this PR.

The `codex-linux-sandbox` crate added to the Cargo workspace as part of
this PR now has the bulk of the Landlock/Seccomp logic, which makes
`core` a bit simpler. Indeed, `core/src/exec_linux.rs` and
`core/src/landlock.rs` were removed/ported as part of this PR. I also
moved the unit tests for this code into an integration test,
`linux-sandbox/tests/landlock.rs`, in which I use
`env!("CARGO_BIN_EXE_codex-linux-sandbox")` as the value for
`codex_linux_sandbox_exe` since `std::env::current_exe()` is not
appropriate in that case.

feat: add support for commands in the Rust TUI (#935 )

Introduces support for slash commands like in the TypeScript CLI. We do
not support the full set of commands yet, but the core abstraction is
there now.

In particular, we have a `SlashCommand` enum and due to thoughtful use
of the [strum](https://crates.io/crates/strum) crate, it requires
minimal boilerplate to add a new command to the list.

The key new piece of UI is `CommandPopup`, though the keyboard events
are still handled by `ChatComposer`. The behavior is roughly as follows:

* if the first character in the composer is `/`, the command popup is
displayed (if you really want to send a message to Codex that starts
with a `/`, simply put a space before the `/`)
* while the popup is displayed, up/down can be used to change the
selection of the popup
* if there is a selection, hitting tab completes the command, but does
not send it
* if there is a selection, hitting enter sends the command
* if the prefix of the composer matches a command, the command will be
visible in the popup so the user can see the description (commands could
take arguments, so additional text may appear after the command name
itself)
