feat(triggers): expand respond-to-review to also fire on COMMENT-type reviews

[aaight]

Summary

• Expand PRReviewSubmittedTrigger.matches() to accept both changes_requested and commented review states, excluding only approved (dismissed reviews are already excluded by the action !== 'submitted' guard)
• Update tests to flip the existing commented-state assertion from false to true, add a new matches test for dismissed state, and add two new handle tests covering commented-state triggering and its null-body fallback
• Update respond-to-review.yaml trigger description to reflect the broader scope

Changed files

File	Change
src/triggers/github/pr-review-submitted.ts	Replace !== 'changes_requested' check with === 'approved' check; update inline comments
tests/unit/triggers/pr-review-submitted.test.ts	Flip commented state assertion; add dismissed/commented handle tests
src/agents/definitions/respond-to-review.yaml	Update trigger description

Safety analysis

• No infinite loop risk — respond-to-review runs as the implementer persona; the trigger requires the reviewer persona. The guard in handle() is unchanged.
• check-suite-success.ts dedup logic that filters out COMMENTED reviews is unrelated and intentionally unchanged.

Test plan

• matches() returns true for changes_requested and commented
• matches() returns false for approved and dismissed (action-filtered)
• handle() returns correct TriggerResult for commented state from reviewer persona
• handle() uses Review: commented fallback when body is null
• All 16 unit tests pass
• Lint and type-check pass

LGTM — Clean, well-scoped change that broadens the review trigger to fire on commented-state reviews in addition to changes_requested.

Verified:

• The matches() logic change from !== 'changes_requested' → === 'approved' correctly excludes only approvals (dismissals are already filtered by the action !== 'submitted' guard above)
• No infinite loop risk: the handle() persona guard (line 61) ensures only reviews from the reviewer persona trigger the agent, while respond-to-review runs as implementer
• The check-suite-success.ts dedup logic that filters out COMMENTED reviews is unaffected and intentionally separate
• The null-body fallback (Review: ${state}) works correctly for the commented state
• All 16 tests pass, covering both matches and handle for the new states
