## Summary
- remove protocol and core support for discovering and listing custom
prompts
- simplify the TUI slash-command flow and command popup to built-in
commands only
- delete obsolete custom prompt tests, helpers, and docs references
- clean up downstream event handling for the removed protocol events
## Why
`argument-comment-lint` had become a PR bottleneck because the repo-wide
lane was still effectively running a `cargo dylint`-style flow across
the workspace instead of reusing Bazel's Rust dependency graph. That
kept the lint enforced, but it threw away the main benefit of moving
this job under Bazel in the first place: metadata reuse and cacheable
per-target analysis in the same shape as Clippy.
This change moves the repo-wide lint onto a native Bazel Rust aspect so
Linux and macOS can lint `codex-rs` without rebuilding the world
crate-by-crate through the wrapper path.
## What Changed
- add a nightly Rust toolchain with `rustc-dev` for Bazel and a
dedicated crate-universe repo for `tools/argument-comment-lint`
- add `tools/argument-comment-lint/driver.rs` and
`tools/argument-comment-lint/lint_aspect.bzl` so Bazel can run the lint
as a custom `rustc_driver`
- switch repo-wide `just argument-comment-lint` and the Linux/macOS
`rust-ci` lanes to `bazel build --config=argument-comment-lint
//codex-rs/...`
- keep the Python/DotSlash wrappers as the package-scoped fallback path
and as the current Windows CI path
- gate the Dylint entrypoint behind a `bazel_native` feature so the
Bazel-native library avoids the `dylint_*` packaging stack
- update the aspect runtime environment so the driver can locate
`rustc_driver` correctly under remote execution
- keep the dedicated `tools/argument-comment-lint` package tests and
wrapper unit tests in CI so the source and packaged entrypoints remain
covered
## Verification
- `python3 -m unittest discover -s tools/argument-comment-lint -p
'test_*.py'`
- `cargo test` in `tools/argument-comment-lint`
- `bazel build
//tools/argument-comment-lint:argument-comment-lint-driver
--@rules_rust//rust/toolchain/channel=nightly`
- `bazel build --config=argument-comment-lint
//codex-rs/utils/path-utils:all`
- `bazel build --config=argument-comment-lint
//codex-rs/rollout:rollout`

This is a follow-up to https://github.com/openai/codex/pull/15922. That
previous PR deleted the old `tui` directory and left the new
`tui_app_server` directory in place. This PR renames `tui_app_server` to
`tui` and fixes up all references.
This PR updates the "PR Babysitter" skill to clarify that non-actionable
review comments should receive a direct reply explaining why no change
is needed, and actionable review comments should be marked "resolved"
after they are addressed.
## Summary
- Moves status surface refresh (`refresh_status_surfaces` /
`refresh_status_line`) from `App` event handlers into `ChatWidget`
setters via a new `refresh_model_dependent_surfaces()` method
- Ensures model-dependent UI stays in sync whenever collaboration mode,
model, or reasoning effort changes, including the footer and terminal
title in both `tui` and `tui_app_server`
- Applies the fix to both `tui` and `tui_app_server` widgets
#15961
## Test plan
- [x] Added snapshot test
`status_line_model_with_reasoning_plan_mode_footer` verifying footer
renders correctly in plan mode
- [x] Added
`terminal_title_model_updates_on_model_change_without_manual_refresh` in
`tui_app_server`
- [ ] Verify switching collaboration modes updates the footer in real
TUI
- [ ] Verify model/reasoning effort changes reflect in the status bar
and terminal title
