Standalone codex-tui no longer prints resume hint on normal exit

Summary

The standalone codex-tui binary no longer prints the exit-time resume hint (To continue this session, run codex resume ...) on a normal exit, even though the main codex CLI still does.

This looks like entrypoint drift rather than the broader SIGINT/abnormal-exit cases.

Repro

1. Start a session with codex-tui
2. Use it enough to materialize a thread id
3. Exit normally
4. Observe that only token usage is printed, with no codex resume ... hint

Expected

Normal codex-tui exits should print the same resume hint as codex, using the thread name when available and otherwise the thread id.

Root Cause

codex-rs/cli/src/main.rs still formats and prints the resume hint on exit, but codex-rs/tui/src/main.rs only printed token usage and dropped the shared resume-command behavior.

Fix Ready

I have a branch with a minimal fix that restores the hint in codex-tui, aligns fatal-exit handling with the main CLI entrypoint, and adds unit coverage.
