Disable empty Cargo test targets (#21584 )

## Summary

`cargo test` has entails both running standard Rust tests and doctests.
It turns out that the doctest discovery is fairly slow, and it's a cost
you pay even for crates that don't include any doctests.

This PR disables doctests with `doctest = false` for crates that lack
any doctests.

For the collection of crates below, this speeds up test execution by
>4x.

E.g., before this PR:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):      1.849 s ±  4.455 s    [User: 0.752 s, System: 1.367 s]
  Range (min … max):    0.418 s … 14.529 s    10 runs
```

And after:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):     428.6 ms ±   6.9 ms    [User: 187.7 ms, System: 219.7 ms]
  Range (min … max):   418.0 ms … 436.8 ms    10 runs
```

For a single crate, with >2x speedup, before:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     491.1 ms ±   9.0 ms    [User: 229.8 ms, System: 234.9 ms]
  Range (min … max):   480.9 ms … 512.0 ms    10 runs
```

And after:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     213.9 ms ±   4.3 ms    [User: 112.8 ms, System: 84.0 ms]
  Range (min … max):   206.8 ms … 221.0 ms    13 runs
```

ci: verify codex-rs Cargo manifests inherit workspace settings (#16353 )

## Why

Bazel clippy now catches lints that `cargo clippy` can still miss when a
crate under `codex-rs` forgets to opt into workspace lints. The concrete
example here was `codex-rs/app-server/tests/common/Cargo.toml`: Bazel
flagged a clippy violation in `models_cache.rs`, but Cargo did not
because that crate inherited workspace package metadata without
declaring `[lints] workspace = true`.

We already mirror the workspace clippy deny list into Bazel after
[#15955](https://github.com/openai/codex/pull/15955), so we also need a
repo-side check that keeps every `codex-rs` manifest opted into the same
workspace settings.

## What changed

- add `.github/scripts/verify_cargo_workspace_manifests.py`, which
parses every `codex-rs/**/Cargo.toml` with `tomllib` and verifies:
  - `version.workspace = true`
  - `edition.workspace = true`
  - `license.workspace = true`
  - `[lints] workspace = true`
- top-level crate names follow the `codex-*` / `codex-utils-*`
conventions, with explicit exceptions for `windows-sandbox-rs` and
`utils/path-utils`
- run that script in `.github/workflows/ci.yml`
- update the current outlier manifests so the check is enforceable
immediately
- fix the newly exposed clippy violations in the affected crates
(`app-server/tests/common`, `file-search`, `feedback`,
`shell-escalation`, and `debug-client`)

chore: add cargo-deny configuration (#7119 )

- add GitHub workflow running cargo-deny on push/PR
- document cargo-deny allowlist with workspace-dep notes and advisory
ignores
- align workspace crates to inherit version/edition/license for
consistent checks

Update submodules version to come from the workspace (#850 )

Update cargo to 2024 edition (#842 )

Some effects of this change:
- New formatting changes across many files. No functionality changes
should occur from that.
- Calls to `set_env` are considered unsafe, since this only happens in
tests we wrap them in `unsafe` blocks

feat: initial import of Rust implementation of Codex CLI in codex-rs/ (#629 )

As stated in `codex-rs/README.md`:

Today, Codex CLI is written in TypeScript and requires Node.js 22+ to
run it. For a number of users, this runtime requirement inhibits
adoption: they would be better served by a standalone executable. As
maintainers, we want Codex to run efficiently in a wide range of
environments with minimal overhead. We also want to take advantage of
operating system-specific APIs to provide better sandboxing, where
possible.

To that end, we are moving forward with a Rust implementation of Codex
CLI contained in this folder, which has the following benefits:

- The CLI compiles to small, standalone, platform-specific binaries.
- Can make direct, native calls to
[seccomp](https://man7.org/linux/man-pages/man2/seccomp.2.html) and
[landlock](https://man7.org/linux/man-pages/man7/landlock.7.html) in
order to support sandboxing on Linux.
- No runtime garbage collection, resulting in lower memory consumption
and better, more predictable performance.

Currently, the Rust implementation is materially behind the TypeScript
implementation in functionality, so continue to use the TypeScript
implmentation for the time being. We will publish native executables via
GitHub Releases as soon as we feel the Rust version is usable.
