• Handle required MCP startup failures across components (#10902)

  Summary
  - add a `required` flag for MCP servers everywhere config/CLI data is
  touched so mandatory helpers can be round-tripped
  - have `codex exec` and `codex app-server` thread start/resume fail fast
  when required MCPs fail to initialize

• feat(app-server): turn/steer API (#10821)

  This PR adds a dedicated `turn/steer` API for appending user input to an
  in-flight turn.
  
  ## Motivation
  Currently, steering in the app is implemented by just calling
  `turn/start` while a turn is running. This has some really weird quirks:
  - Client gets back a new `turn.id`, even though streamed
  events/approvals remained tied to the original active turn ID.
  - All the various turn-level override params on `turn/start` do not
  apply to the "steer", and would only apply to the next real turn.
  - There can also be a race condition where the client thinks the turn is
  active but the server has already completed it, so there might be bugs
  if the client has baked in some client-specific behavior thinking it's a
  steer when in fact the server kicked off a new turn. This is
  particularly possible when running a client against a remote app-server.
  
  Having a dedicated `turn/steer` API eliminates all those quirks.
  
  `turn/steer` behavior:
  - Requires an active turn on threadId. Returns a JSON-RPC error if there
  is no active turn.
  - If expectedTurnId is provided, it must match the active turn (more
  useful when connecting to a remote app-server).
  - Does not emit `turn/started`.
  - Does not accept turn overrides (`cwd`, `model`, `sandbox`, etc.) or
  `outputSchema` to accurately reflect that these are not applied when
  steering.

• Add app-server transport layer with websocket support (#10693)

  - Adds --listen <URL> to codex app-server with two listen modes:
        - stdio:// (default, existing behavior)
        - ws://IP:PORT (new websocket transport)
    - Refactors message routing to be connection-aware:
  - Tracks per-connection session state (initialize/experimental
  capability)
        - Routes responses/errors to the originating connection
  - Broadcasts server notifications/requests to initialized connections
  - Updates initialization semantics to be per connection (not
  process-global), and updates app-server docs accordingly.
  - Adds websocket accept/read/write handling (JSON-RPC per text frame,
  ping/pong handling, connection lifecycle events).
  
  Testing
  
  - Unit tests for transport URL parsing and targeted response/error
  routing.
    - New websocket integration test validating:
        - per-connection initialization requirements
        - no cross-connection response leakage
        - same request IDs on different connections route independently.

• Leverage state DB metadata for thread summaries (#10621)

  Summary:
  - read conversation summaries and cwd info from the state DB when
  possible so we no longer rely on rollout files for metadata and avoid
  extra I/O
  - persist CLI version in thread metadata, surface it through summary
  builders, and add the necessary DB migration hooks
  - simplify thread listing by using enriched state DB data directly
  rather than reading rollout heads
  
  Testing:

• feat(app-server, core): allow text + image content items for dynamic tool outputs (#10567)

  Took over the work that @aaronl-openai started here:
  https://github.com/openai/codex/pull/10397
  
  Now that app-server clients are able to set up custom tools (called
  `dynamic_tools` in app-server), we should expose a way for clients to
  pass in not just text, but also image outputs. This is something the
  Responses API already supports for function call outputs, where you can
  pass in either a string or an array of content outputs (text, image,
  file):
  https://platform.openai.com/docs/api-reference/responses/create#responses_create-input-input_item_list-item-function_tool_call_output-output-array-input_image
  
  So let's just plumb it through in Codex (with the caveat that we only
  support text and image for now). This is implemented end-to-end across
  app-server v2 protocol types and core tool handling.
  
  ## Breaking API change
  NOTE: This introduces a breaking change with dynamic tools, but I think
  it's ok since this concept was only recently introduced
  (https://github.com/openai/codex/pull/9539) and it's better to get the
  API contract correct. I don't think there are any real consumers of this
  yet (not even the Codex App).
  
  Old shape:
  `{ "output": "dynamic-ok", "success": true }`
  
  New shape:
  ```
  {
      "contentItems": [
        { "type": "inputText", "text": "dynamic-ok" },
        { "type": "inputImage", "imageUrl": "data:image/png;base64,AAA" }
      ]
    "success": true
  }
  ```

• Fix test_shell_command_interruption flake (#10649)

  ## Human summary
  Sandboxing (specifically `LandlockRestrict`) is means that e.g. `sleep
  10` fails immediately. Therefore it cannot be interrupted.
  
  In suite::interrupt::test_shell_command_interruption, sleep 10 is issued
  at 17:28:16.554 (ToolCall: shell_command {"command":"sleep 10"...}),
  then fails at 17:28:16.589 with duration_ms=34, success=false,
  exit_code=101, and
      Sandbox(LandlockRestrict).
  
  ## Codex summary
  - set `sandbox_mode = "danger-full-access"` in `interrupt` and
  `v2/turn_interrupt` integration tests
  - set `sandbox: Some(SandboxMode::DangerFullAccess)` in
  `test_codex_jsonrpc_conversation_flow`
  - set `sandbox_policy: Some(SandboxPolicy::DangerFullAccess)` in
  `command_execution_notifications_include_process_id`
  
  ## Why
  On some Linux CI environments, command execution fails immediately with
  `LandlockRestrict` when sandboxed. These tests are intended to validate
  JSON-RPC/task lifecycle behavior (interrupt semantics, command
  notification shape/process id, request flow), but early sandbox startup
  failure changes turn flow and can trigger extra follow-up requests,
  causing flakes.
  
  This change removes environment-specific sandbox startup dependency from
  these tests while preserving their primary intent.
  
  ## Testing
  - not run in this environment (per request)

• feat(linux-sandbox): add bwrap support (#9938)

  ## Summary
  This PR introduces a gated Bubblewrap (bwrap) Linux sandbox path. The
  curent Linux sandbox path relies on in-process restrictions (including
  Landlock). Bubblewrap gives us a more uniform filesystem isolation
  model, especially explicit writable roots with the option to make some
  directories read-only and granular network controls.
  
  This is behind a feature flag so we can validate behavior safely before
  making it the default.
  
  - Added temporary rollout flag:
    - `features.use_linux_sandbox_bwrap`
  - Preserved existing default path when the flag is off.
  - In Bubblewrap mode:
  - Added internal retry without /proc when /proc mount is not permitted
  by the host/container.

• fix(app-server): fix approval events in review mode (#10416)

  One of our partners flagged that they were seeing the wrong order of
  events when running `review/start` with command exec approvals:
  ```
  {"method":"item/commandExecution/requestApproval","id":0,"params":{"threadId":"019c0b6b-6a42-7c02-99c4-98c80e88ac27","turnId":"0","itemId":"0","reason":"`/bin/zsh -lc 'git show b7a92b4eacf262c575f26b1e1ed621a357642e55 --stat'` requires approval: Xcode-required approval: Require explicit user confirmation for all commands.","proposedExecpolicyAmendment":null}}
  
  {"method":"item/started","params":{"item":{"type":"commandExecution","id":"call_AEjlbHqLYNM7kbU3N6uw1CNi","command":"/bin/zsh -lc 'git show b7a92b4eacf262c575f26b1e1ed621a357642e55 --stat'","cwd":"/Users/devingreen/Desktop/SampleProject","processId":null,"status":"inProgress","commandActions":[{"type":"unknown","command":"git show b7a92b4eacf262c575f26b1e1ed621a357642e55 --stat"}],"aggregatedOutput":null,"exitCode":null,"durationMs":null},"threadId":"019c0b6b-6a42-7c02-99c4-98c80e88ac27","turnId":"0"}}
  ```
  
  **Key fix**: In the review sub‑agent delegate we were forwarding exec
  (and patch) approvals using the parent turn id (`parent_ctx.sub_id`) as
  the approval call_id. That made
  `item/commandExecution/requestApproval.itemId` differ from the actual
  `item/started` id. We now forward the sub‑agent’s `call_id` from the
  approval event instead, so the approval item id matches the
  commandExecution item id in review flows.
  
  Here’s the expected event order for an inline `review/start` that
  triggers an exec approval after this fix:
  1. Response to review/start (JSON‑RPC response)
  - Includes `turn` (status inProgress) and `review_thread_id` (same as
  parent thread for inline).
  2. `turn/started` notification
    - turnId is the review turn id (e.g., "0").
  3. `item/started` → EnteredReviewMode
    - item.id == turnId, marks entry into review mode.
  4. `item/started` → commandExecution
    - item.id == <call_id> (e.g., "review-call-1"), status: inProgress.
  5. `item/commandExecution/requestApproval` request
    - JSON‑RPC request (not a notification).
    - params.itemId == <call_id> and params.turnId == turnId.
  6. Client replies to approval request (Approved / Declined / etc).
  7. If approved:
    - Optional `item/commandExecution/outputDelta` notifications.
    - `item/completed` → commandExecution with status and exitCode.
  8. Review finishes:
    - `item/started` → ExitedReviewMode
    - `item/completed` → ExitedReviewMode
    - (Agent message items may also appear, depending on review output.)
  9. `turn/completed` notification
  
  The key being #4 and #5 are now in the proper order with the correct
  item id.

• Cleanup collaboration mode variants (#10404)

  ## Summary
  
  This PR simplifies collaboration modes to the visible set `default |
  plan`, while preserving backward compatibility for older partners that
  may still send legacy mode
  names.
  
  Specifically:
  - Renames the old Code behavior to **Default**.
  - Keeps **Plan** as-is.
  - Removes **Custom** mode behavior (fallbacks now resolve to Default).
  - Keeps `PairProgramming` and `Execute` internally for compatibility
  plumbing, while removing them from schema/API and UI visibility.
  - Adds legacy input aliasing so older clients can still send old mode
  names.
  
  ## What Changed
  
  1. Mode enum and compatibility
  - `ModeKind` now uses `Plan` + `Default` as active/public modes.
  - `ModeKind::Default` deserialization accepts legacy values:
    - `code`
    - `pair_programming`
    - `execute`
    - `custom`
  - `PairProgramming` and `Execute` variants remain in code but are hidden
  from protocol/schema generation.
  - `Custom` variant is removed; previous custom fallbacks now map to
  `Default`.
  
  2. Collaboration presets and templates
  - Built-in presets now return only:
    - `Plan`
    - `Default`
  - Template rename:
    - `core/templates/collaboration_mode/code.md` -> `default.md`
  - `execute.md` and `pair_programming.md` remain on disk but are not
  surfaced in visible preset lists.
  
  3. TUI updates
  - Updated user-facing naming and prompts from “Code” to “Default”.
  - Updated mode-cycle and indicator behavior to reflect only visible
  `Plan` and `Default`.
  - Updated corresponding tests and snapshots.
  
  4. request_user_input behavior
  - `request_user_input` remains allowed only in `Plan` mode.
  - Rejection messaging now consistently treats non-plan modes as
  `Default`.
  
  5. Schemas
  - Regenerated config and app-server schemas.
  - Public schema types now advertise mode values as:
    - `plan`
    - `default`
  
  ## Backward Compatibility Notes
  
  - Incoming legacy mode names (`code`, `pair_programming`, `execute`,
  `custom`) are accepted and coerced to `default`.
  - Outgoing/public schema surfaces intentionally expose only `plan |
  default`.
  - This allows tolerant ingestion of older partner payloads while
  standardizing new integrations on the reduced mode set.

• [Codex][CLI] Gate image inputs by model modalities (#10271)

  ###### Summary
  
  - Add input_modalities to model metadata so clients can determine
  supported input types.
  - Gate image paste/attach in TUI when the selected model does not
  support images.
  - Block submits that include images for unsupported models and show a
  clear warning.
  - Propagate modality metadata through app-server protocol/model-list
  responses.
    - Update related tests/fixtures.
  
    ###### Rationale
  
    - Models support different input modalities.
  - Clients need an explicit capability signal to prevent unsupported
  requests.
  - Backward-compatible defaults preserve existing behavior when modality
  metadata is absent.
  
    ###### Scope
  
    - codex-rs/protocol, codex-rs/core, codex-rs/tui
    - codex-rs/app-server-protocol, codex-rs/app-server
    - Generated app-server types / schema fixtures
  
    ###### Trade-offs
  
  - Default behavior assumes text + image when field is absent for
  compatibility.
    - Server-side validation remains the source of truth.
  
    ###### Follow-up
  
  - Non-TUI clients should consume input_modalities to disable unsupported
  attachments.
  - Model catalogs should explicitly set input_modalities for text-only
  models.
  
    ###### Testing
  
    - cargo fmt --all
    - cargo test -p codex-tui
    - env -u GITHUB_APP_KEY cargo test -p codex-core --lib
    - just write-app-server-schema
  - cargo run -p codex-cli --bin codex -- app-server generate-ts --out
  app-server-types
    - test against local backend

• feat: replace custom mcp-types crate with equivalents from rmcp (#10349)

  We started working with MCP in Codex before
  https://crates.io/crates/rmcp was mature, so we had our own crate for
  MCP types that was generated from the MCP schema:
  
  
  https://github.com/openai/codex/blob/8b95d3e082376f4cb23e92641705a22afb28a9da/codex-rs/mcp-types/README.md
  
  Now that `rmcp` is more mature, it makes more sense to use their MCP
  types in Rust, as they handle details (like the `_meta` field) that our
  custom version ignored. Though one advantage that our custom types had
  is that our generated types implemented `JsonSchema` and `ts_rs::TS`,
  whereas the types in `rmcp` do not. As such, part of the work of this PR
  is leveraging the adapters between `rmcp` types and the serializable
  types that are API for us (app server and MCP) introduced in #10356.
  
  Note this PR results in a number of changes to
  `codex-rs/app-server-protocol/schema`, which merit special attention
  during review. We must ensure that these changes are still
  backwards-compatible, which is possible because we have:
  
  ```diff
  - export type CallToolResult = { content: Array<ContentBlock>, isError?: boolean, structuredContent?: JsonValue, };
  + export type CallToolResult = { content: Array<JsonValue>, structuredContent?: JsonValue, isError?: boolean, _meta?: JsonValue, };
  ```
  
  so `ContentBlock` has been replaced with the more general `JsonValue`.
  Note that `ContentBlock` was defined as:
  
  ```typescript
  export type ContentBlock = TextContent | ImageContent | AudioContent | ResourceLink | EmbeddedResource;
  ```
  
  so the deletion of those individual variants should not be a cause of
  great concern.
  
  Similarly, we have the following change in
  `codex-rs/app-server-protocol/schema/typescript/Tool.ts`:
  
  ```
  - export type Tool = { annotations?: ToolAnnotations, description?: string, inputSchema: ToolInputSchema, name: string, outputSchema?: ToolOutputSchema, title?: string, };
  + export type Tool = { name: string, title?: string, description?: string, inputSchema: JsonValue, outputSchema?: JsonValue, annotations?: JsonValue, icons?: Array<JsonValue>, _meta?: JsonValue, };
  ```
  
  so:
  
  - `annotations?: ToolAnnotations` ➡️ `JsonValue`
  - `inputSchema: ToolInputSchema` ➡️ `JsonValue`
  - `outputSchema?: ToolOutputSchema` ➡️ `JsonValue`
  
  and two new fields: `icons?: Array<JsonValue>, _meta?: JsonValue`

• feat: experimental flags (#10231)

  ## Problem being solved
  - We need a single, reliable way to mark app-server API surface as
  experimental so that:
    1. the runtime can reject experimental usage unless the client opts in
  2. generated TS/JSON schemas can exclude experimental methods/fields for
  stable clients.
  
  Right now that’s easy to drift or miss when done ad-hoc.
  
  ## How to declare experimental methods and fields
  - **Experimental method**: add `#[experimental("method/name")]` to the
  `ClientRequest` variant in `client_request_definitions!`.
  - **Experimental field**: on the params struct, derive `ExperimentalApi`
  and annotate the field with `#[experimental("method/name.field")]` + set
  `inspect_params: true` for the method variant so
  `ClientRequest::experimental_reason()` inspects params for experimental
  fields.
  
  ## How the macro solves it
  - The new derive macro lives in
  `codex-rs/codex-experimental-api-macros/src/lib.rs` and is used via
  `#[derive(ExperimentalApi)]` plus `#[experimental("reason")]`
  attributes.
  - **Structs**:
  - Generates `ExperimentalApi::experimental_reason(&self)` that checks
  only annotated fields.
    - The “presence” check is type-aware:
      - `Option<T>`: `is_some_and(...)` recursively checks inner.
      - `Vec`/`HashMap`/`BTreeMap`: must be non-empty.
      - `bool`: must be `true`.
      - Other types: considered present (returns `true`).
  - Registers each experimental field in an `inventory` with `(type_name,
  serialized field name, reason)` and exposes `EXPERIMENTAL_FIELDS` for
  that type. Field names are converted from `snake_case` to `camelCase`
  for schema/TS filtering.
  - **Enums**:
  - Generates an exhaustive `match` returning `Some(reason)` for annotated
  variants and `None` otherwise (no wildcard arm).
  - **Wiring**:
  - Runtime gating uses `ExperimentalApi::experimental_reason()` in
  `codex-rs/app-server/src/message_processor.rs` to reject requests unless
  `InitializeParams.capabilities.experimental_api == true`.
  - Schema/TS export filters use the inventory list and
  `EXPERIMENTAL_CLIENT_METHODS` from `client_request_definitions!` to
  strip experimental methods/fields when `experimental_api` is false.

• Bump thread updated_at on unarchive to refresh sidebar ordering (#10280)

  ## Summary
  - Touch restored rollout files on `thread/unarchive` so `updatedAt`
  reflects the unarchive time.
  - Add a regression test to ensure unarchiving bumps `updated_at` from an
  old mtime.
  
  ## Notes
  This fixes the UX issue where unarchived old threads don’t reappear near
  the top of recent threads.

• chore: rename ChatGpt -> Chatgpt in type names (#10244)

  When using ChatGPT in names of types, we should be consistent, so this
  renames some types with `ChatGpt` in the name to `Chatgpt`. From
  https://rust-lang.github.io/api-guidelines/naming.html:
  
  > In `UpperCamelCase`, acronyms and contractions of compound words count
  as one word: use `Uuid` rather than `UUID`, `Usize` rather than `USize`
  or `Stdin` rather than `StdIn`. In `snake_case`, acronyms and
  contractions are lower-cased: `is_xid_start`.
  
  This PR updates existing uses of `ChatGpt` and changes them to
  `Chatgpt`. Though in all cases where it could affect the wire format, I
  visually inspected that we don't change anything there. That said, this
  _will_ change the codegen because it will affect the spelling of type
  names.
  
  For example, this renames `AuthMode::ChatGPT` to `AuthMode::Chatgpt` in
  `app-server-protocol`, but the wire format is still `"chatgpt"`.
  
  This PR also updates a number of types in `codex-rs/core/src/auth.rs`.

• Plan mode: stream proposed plans, emit plan items, and render in TUI (#9786)

  ## Summary
  - Stream proposed plans in Plan Mode using `<proposed_plan>` tags parsed
  in core, emitting plan deltas plus a plan `ThreadItem`, while stripping
  tags from normal assistant output.
  - Persist plan items and rebuild them on resume so proposed plans show
  in thread history.
  - Wire plan items/deltas through app-server protocol v2 and render a
  dedicated proposed-plan view in the TUI, including the “Implement this
  plan?” prompt only when a plan item is present.
  
  ## Changes
  
  ### Core (`codex-rs/core`)
  - Added a generic, line-based tag parser that buffers each line until it
  can disprove a tag prefix; implements auto-close on `finish()` for
  unterminated tags. `codex-rs/core/src/tagged_block_parser.rs`
  - Refactored proposed plan parsing to wrap the generic parser.
  `codex-rs/core/src/proposed_plan_parser.rs`
  - In plan mode, stream assistant deltas as:
    - **Normal text** → `AgentMessageContentDelta`
    - **Plan text** → `PlanDelta` + `TurnItem::Plan` start/completion  
    (`codex-rs/core/src/codex.rs`)
  - Final plan item content is derived from the completed assistant
  message (authoritative), not necessarily the concatenated deltas.
  - Strips `<proposed_plan>` blocks from assistant text in plan mode so
  tags don’t appear in normal messages.
  (`codex-rs/core/src/stream_events_utils.rs`)
  - Persist `ItemCompleted` events only for plan items for rollout replay.
  (`codex-rs/core/src/rollout/policy.rs`)
  - Guard `update_plan` tool in Plan Mode with a clear error message.
  (`codex-rs/core/src/tools/handlers/plan.rs`)
  - Updated Plan Mode prompt to:  
    - keep `<proposed_plan>` out of non-final reasoning/preambles  
    - require exact tag formatting  
    - allow only one `<proposed_plan>` block per turn  
    (`codex-rs/core/templates/collaboration_mode/plan.md`)
  
  ### Protocol / App-server protocol
  - Added `TurnItem::Plan` and `PlanDeltaEvent` to core protocol items.
  (`codex-rs/protocol/src/items.rs`, `codex-rs/protocol/src/protocol.rs`)
  - Added v2 `ThreadItem::Plan` and `PlanDeltaNotification` with
  EXPERIMENTAL markers and note that deltas may not match the final plan
  item. (`codex-rs/app-server-protocol/src/protocol/v2.rs`)
  - Added plan delta route in app-server protocol common mapping.
  (`codex-rs/app-server-protocol/src/protocol/common.rs`)
  - Rebuild plan items from persisted `ItemCompleted` events on resume.
  (`codex-rs/app-server-protocol/src/protocol/thread_history.rs`)
  
  ### App-server
  - Forward plan deltas to v2 clients and map core plan items to v2 plan
  items. (`codex-rs/app-server/src/bespoke_event_handling.rs`,
  `codex-rs/app-server/src/codex_message_processor.rs`)
  - Added v2 plan item tests.
  (`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
  
  ### TUI
  - Added a dedicated proposed plan history cell with special background
  and padding, and moved “• Proposed Plan” outside the highlighted block.
  (`codex-rs/tui/src/history_cell.rs`, `codex-rs/tui/src/style.rs`)
  - Only show “Implement this plan?” when a plan item exists.
  (`codex-rs/tui/src/chatwidget.rs`,
  `codex-rs/tui/src/chatwidget/tests.rs`)
  
  <img width="831" height="847" alt="Screenshot 2026-01-29 at 7 06 24 PM"
  src="https://github.com/user-attachments/assets/69794c8c-f96b-4d36-92ef-c1f5c3a8f286"
  />
  
  ### Docs / Misc
  - Updated protocol docs to mention plan deltas.
  (`codex-rs/docs/protocol_v1.md`)
  - Minor plumbing updates in exec/debug clients to tolerate plan deltas.
  (`codex-rs/debug-client/src/reader.rs`, `codex-rs/exec/...`)
  
  ## Tests
  - Added core integration tests:
    - Plan mode strips plan from agent messages.
    - Missing `</proposed_plan>` closes at end-of-message.  
    (`codex-rs/core/tests/suite/items.rs`)
  - Added unit tests for generic tag parser (prefix buffering, non-tag
  lines, auto-close). (`codex-rs/core/src/tagged_block_parser.rs`)
  - Existing app-server plan item tests in v2.
  (`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
  
  ## Notes / Behavior
  - Plan output no longer appears in standard assistant text in Plan Mode;
  it streams via `PlanDelta` and completes as a `TurnItem::Plan`.
  - The final plan item content is authoritative and may diverge from
  streamed deltas (documented as experimental).
  - Reasoning summaries are not filtered; prompt instructs the model not
  to include `<proposed_plan>` outside the final plan message.

• Load exec policy rules from requirements (#10190)

  `requirements.toml` should be able to specify rules which always run. 
  
  My intention here was that these rules could only ever be restrictive,
  which means the decision can be "prompt" or "forbidden" but never
  "allow". A requirement of "you must always allow this command" didn't
  make sense to me, but happy to be gaveled otherwise.
  
  Rules already applies the most restrictive decision, so we can safely
  merge these with rules found in other config folders.

• feat: refactor CodexAuth so invalid state cannot be represented (#10208)

  Previously, `CodexAuth` was defined as follows:
  
  
  https://github.com/openai/codex/blob/d550fbf41afc09d7d7b5ac813aea38de07b2a73f/codex-rs/core/src/auth.rs#L39-L46
  
  But if you looked at its constructors, we had creation for
  `AuthMode::ApiKey` where `storage` was built using a nonsensical path
  (`PathBuf::new()`) and `auth_dot_json` was `None`:
  
  
  https://github.com/openai/codex/blob/d550fbf41afc09d7d7b5ac813aea38de07b2a73f/codex-rs/core/src/auth.rs#L212-L220
  
  By comparison, when `AuthMode::ChatGPT` was used, `api_key` was always
  `None`:
  
  
  https://github.com/openai/codex/blob/d550fbf41afc09d7d7b5ac813aea38de07b2a73f/codex-rs/core/src/auth.rs#L665-L671
  
  https://github.com/openai/codex/pull/10012 took things further because
  it introduced a new `ChatgptAuthTokens` variant to `AuthMode`, which is
  important in when invoking `account/login/start` via the app server, but
  most logic _internal_ to the app server should just reason about two
  `AuthMode` variants: `ApiKey` and `ChatGPT`.
  
  This PR tries to clean things up as follows:
  
  - `LoginAccountParams` and `AuthMode` in `codex-rs/app-server-protocol/`
  both continue to have the `ChatgptAuthTokens` variant, though it is used
  exclusively for the on-the-wire messaging.
  - `codex-rs/core/src/auth.rs` now has its own `AuthMode` enum, which
  only has two variants: `ApiKey` and `ChatGPT`.
  - `CodexAuth` has been changed from a struct to an enum. It is a
  disjoint union where each variant (`ApiKey`, `ChatGpt`, and
  `ChatGptAuthTokens`) have only the associated fields that make sense for
  that variant.
