Extends the single-terminal-decision machinery (#211) to session-level
hard-stop semantics:
- terminal_review_hard_stop_reasons: after a live terminal verdict, only
the merge sequence for the same approved PR may continue; REQUEST_CHANGES
stops the run; operator-approved corrections re-open the review path
only, never a cross-PR merge.
- gitea_merge_pr: new Gate 2b consults the hard-stop before any API call,
so a run can never verdict one PR and merge another.
- gitea_mark_final_review_decision: hard-stop check with explicit stop
guidance naming the consumed terminal mutation; plus duplicate
REQUEST_CHANGES suppression — an unresolved request-changes at the
current head SHA refuses a second request-changes (fail closed when
feedback cannot be verified).
- tests/test_terminal_review_hard_stop.py: 13 tests covering the
acceptance criteria; existing TestSubmitPrReview setups stub the new
feedback fetch.
