test-tui

You can start and use Codex TUI to verify changes.

Important notes:

Start interactively.
Always set RUST_LOG="trace" when starting the process.
Pass -c log_dir=<some_temp_dir> argument to have logs written to a specific directory to help with debugging.
When sending a test message programmatically, send text first, then send Enter in a separate write (do not send text + Enter in one burst).
Use just codex target to run - just codex -c ...
