ci(actions): split claude pr-review concurrency queues

[mega-putin]

Generated by engineer-agent — review carefully before merging.

Summary

Update the pr-review concurrency group to separate pull_request code runs from issue_comment runs while preserving cancel-in-progress: false, preventing comment edits from canceling queued reviews for new commit SHAs.

Claude review status

Living comment — rewritten in place. The review workflow keeps this single comment up to date instead of posting a new one each round, so it always describes the latest reviewed commit and the earlier text is intentionally gone. No reply is needed here; reply to a finding in its own review thread, and answer an open question in a reply on this PR. The next review round reconciles your answer.

This round did not publish: MODEL_NO_OUTPUT in phase compile. Anything listed below is from the last round that did. Re-run the workflow or push a new commit to try again.

🧬 Mutation testing — ✅ PASS

Nothing to test — no mutants were generated on the changed lines.

🧬 Mutation testing

No results at target/mutants/mutants.out — nothing was mutated (e.g. no mutatable changes).

[mega-putin]

No actionable review feedback was present. The mutation-testing comment is a passing status report, so I made no code changes and created no commit.

🔧 Pushed CI fixes.

Agent log

Created an empty CI retrigger commit because the remaining `PR Triage` failure was stale: newer `PR Triage` runs had already passed, but an older failed run was still being reported and reruns were blocked by GitHub permissions.

Commit: `a945d50 fix CI: retrigger PR triage`

The worktree is clean, and the diff against `origin/main` is still only the requested one-line workflow change.
