Session Handoff [auto-1425]: Detect CodeRabbit's Command-Reply Rate Limit in pr_review.py for #1425 #3127

Next steps, in priority order

1. Fix pr_review.py Detects Only CodeRabbit's Auto-Review Rate Limit, Not the One It Returns to an Explicit Review Command #1425: make scripts/pr_review.py detect CodeRabbit's rate-limit reply to an explicit @coderabbitai review command, and surface it the same way the auto-review notice already surfaces, through rate_limited_by and the digest's other_rate_limited= field. Today RATE_LIMITED matches only the auto-generated comment: rate limited by <service> --> marker. The command-reply shape is an auto-generated reply by CodeRabbit marker followed by an Action not completed block reading Review rate limited., and it names no service in the marker, so attribute the service from the commenting login (a known reviewer in OTHER_REVIEWERS) rather than from the marker. Keep the reading structural (markers and the block's fixed text), never free prose, per the comment above RATE_LIMITED. Done looks like a pull request into develop carrying Closes on promotion: #1425, with tests in tests/test_pr_review.py feeding a constructed command-reply comment that now reads as rate limited, the existing auto-review marker still reading as before, and a CodeRabbit comment that is neither (for example an ordinary review summary) reading as not rate limited. Surface it the same way means the same field and the same reading. The issue's side question, whether a limit with no stated retry time should read differently from one with a countdown, is not part of this lane, so leave that reading unchanged and do not file it as done.

External blockers

None known.

Internal dependencies

None. #2252 also edits pr_review.py's reviewer reading, for Qodo, and needs a design decision first, so it does not belong in this lane.

State

No branch or worktree exists for this lane yet. develop is thirteen squash commits ahead of main, none of them naming #1425. No open pull request exists in the repository.

Parked decision queue

None.
