Tackle GitHub PR comments

Review threads and their resolved state live only in GraphQL. The REST API cannot read isResolved and cannot resolve a thread, and gh pr view --comments shows issue comments while hiding inline review threads entirely. So this skill drives everything through GraphQL via scripts/gh-pr-comments.ts, authenticated with gh auth token.

The loop

1. Fetch — list the unresolved threads.
2. Verify each claim before acting on it. Bot reviewers are often right and sometimes confidently wrong. Read the code the comment points at.
3. Fix what is real, in a commit separate from the original work so the reviewer can see what changed in response.
4. Reply to every thread, including ones you are declining.
5. Resolve each thread.
6. Verify nothing is left open, then push.
