Duplicate of #1424, which already reported this exact deadlock (inherited CodeRabbit label gate skipping auto-review) with full evidence and acceptance criteria, and already has a fix PR in flight. See also #1482 for a follow-up noting the first fix attempt (#1425) didn't fully resolve it — worth checking before proposing another fix here.

Duplicate of #1424. Same CodeRabbit inherited-label-gate deadlock, same proposed fix; #1424 is the earlier, fully-documented report (evidence, root cause, acceptance criteria). Closing to keep this tracked in one issue.
