What platform is your computer?

Linux x86_64

What terminal emulator and version are you using (if applicable)?

tmux 3.5a

What issue are you seeing?

/review can send stale reasoning.effort = xhigh after switching to gpt-5.1-codex-mini, causing:

Unsupported value: "xhigh" is not supported with the "gpt-5.1-codex-mini" model. Supported values are: "low", "medium", and "high".

What steps can reproduce the bug?

1. Start a session on gpt-5.3-codex-spark with effort xhigh.
2. Switch to gpt-5.1-codex-mini with effort high.
3. Run /review.
4. Observe unsupported_value on reasoning.effort.

What is the expected behavior?

/review should use current runtime model/effort (or clamp to supported effort for the selected model).
