Review on request

The review file starts with `Approved` or `Changes requested` instead of `Yes`/`No`/`With fixes`. The match is still the whole trimmed first line; `run.ts` prepends ✅, 🛑, or 💬 when posting, so the mark never takes part in the match.

Verified: `deno fmt`, `deno lint`, `deno check` pass; a scratch run of the matcher maps `Approved` → APPROVED, `Changes requested` → REQUEST_CHANGES, and `Approved, mostly`, `✅ Approved`, `Yes` → COMMENT.
