Michael Bolin 2616c7cf12 ci: add Bazel clippy workflow for codex-rs (#15955)
## Why
`bazel.yml` already builds and tests the Bazel graph, but `rust-ci.yml`
still runs `cargo clippy` separately. This PR starts the transition to a
Bazel-backed lint lane for `codex-rs` so we can eventually replace the
duplicate Rust build, test, and lint work with Bazel while explicitly
keeping the V8 Bazel path out of scope for now.

To make that lane practical, the workflow also needs to look like the
Bazel job we already trust. That means sharing the common Bazel setup
and invocation logic instead of hand-copying it, and covering the arm64
macOS path in addition to Linux.

Landing the workflow green also required fixing the first lint findings
that Bazel surfaced and adding the matching local entrypoint.

## What changed
- add a reusable `build:clippy` config to `.bazelrc` and export
`codex-rs/clippy.toml` from `codex-rs/BUILD.bazel` so Bazel can run the
repository's existing Clippy policy
- add `just bazel-clippy` so the local developer entrypoint matches the
new CI lane
- extend `.github/workflows/bazel.yml` with a dedicated Bazel clippy job
for `codex-rs`, scoped to `//codex-rs/... -//codex-rs/v8-poc:all`
- run that clippy job on Linux x64 and arm64 macOS
- factor the shared Bazel workflow setup into
`.github/actions/setup-bazel-ci/action.yml` and the shared Bazel
invocation logic into `.github/scripts/run-bazel-ci.sh` so the clippy
and build/test jobs stay aligned
- fix the first Bazel-clippy findings needed to keep the lane green,
including the cross-target `cmsghdr::cmsg_len` normalization in
`codex-rs/shell-escalation/src/unix/socket.rs` and the no-`voice-input`
dead-code warnings in `codex-rs/tui` and `codex-rs/tui_app_server`

## Verification
- `just bazel-clippy`
- `RUNNER_OS=macOS ./.github/scripts/run-bazel-ci.sh -- build
--config=clippy --build_metadata=COMMIT_SHA=local-check
--build_metadata=TAG_job=clippy -- //codex-rs/...
-//codex-rs/v8-poc:all`
- `bazel build --config=clippy
//codex-rs/shell-escalation:shell-escalation`
- `CARGO_TARGET_DIR=/tmp/codex4-shell-escalation-test cargo test -p
codex-shell-escalation`
- `ruby -e 'require "yaml";
YAML.load_file(".github/workflows/bazel.yml");
YAML.load_file(".github/actions/setup-bazel-ci/action.yml")'`

## Notes
- `CARGO_TARGET_DIR=/tmp/codex4-tui-app-server-test cargo test -p
codex-tui-app-server` still hits existing guardian-approvals test and
snapshot failures unrelated to this PR's Bazel-clippy changes.
