- Add 3 REST calls to Promise.all for PRs (listComments, listReviews,
listReviewComments) and 1 for issues (listComments)
- Add mapping helpers: mapRestComments, mapRestReviewComments,
mapRestReviews (groups inline comments by pull_request_review_id)
- Import and apply TOCTOU filtering (filterCommentsToTriggerTime,
filterReviewsToTriggerTime) and actor filtering from GitHub fetcher
- Add image processing pipeline via downloadCommentImages (no-op on
Forgejo due to URL pattern mismatch, architecturally correct)
- Deep-clone reviews before filtering to preserve contextData immutability
- Update test suite: 51 tests covering mapping helpers, full fetch
flow, TOCTOU filtering, actor filtering, and contextData immutability
- Updated PRD checkboxes for M4b completion
Progress: 44% complete (4/9 milestones) - next: M5 or M3
