fix: close Bazel argument-comment-lint CI gaps (#16253)

## Why

The Bazel-backed `argument-comment-lint` CI path had two gaps:

- Bazel wildcard target expansion skipped inline unit-test crates from
`src/` modules because the generated `*-unit-tests-bin` `rust_test`
targets are tagged `manual`.
- `argument-comment-mismatch` was still only a warning in the Bazel and
packaged-wrapper entrypoints, so a typoed `/*param_name*/` comment could
still pass CI even when the lint detected it.

That left CI blind to real linux-sandbox examples, including the missing
`/*local_port*/` comment in
`codex-rs/linux-sandbox/src/proxy_routing.rs` and typoed argument
comments in `codex-rs/linux-sandbox/src/landlock.rs`.

## What Changed

- Added `tools/argument-comment-lint/list-bazel-targets.sh` so Bazel
lint runs cover `//codex-rs/...` plus the manual `rust_test`
`*-unit-tests-bin` targets.
- Updated `just argument-comment-lint`, `rust-ci.yml`, and
`rust-ci-full.yml` to use that helper.
- Promoted both `argument-comment-mismatch` and
`uncommented-anonymous-literal-argument` to errors in every strict
entrypoint:
  - `tools/argument-comment-lint/lint_aspect.bzl`
  - `tools/argument-comment-lint/src/bin/argument-comment-lint.rs`
  - `tools/argument-comment-lint/wrapper_common.py`
- Added wrapper/bin coverage for the stricter lint flags and documented
the behavior in `tools/argument-comment-lint/README.md`.
- Fixed the now-covered callsites in
`codex-rs/linux-sandbox/src/proxy_routing.rs`,
`codex-rs/linux-sandbox/src/landlock.rs`, and
`codex-rs/core/src/shell_snapshot_tests.rs`.

This keeps the Bazel target expansion narrow while making the Bazel and
prebuilt-linter paths enforce the same strict lint set.

## Verification

- `python3 -m unittest discover -s tools/argument-comment-lint -p
'test_*.py'`
- `cargo +nightly-2025-09-18 test --manifest-path
tools/argument-comment-lint/Cargo.toml`
- `just argument-comment-lint`
