Watch an ASC CLI pull request

Run one idempotent follow-up pass. Preserve the existing PR context instead of restarting the full audit.

Recheck current state

1. Resolve the exact PR and compare its current head SHA with the last audited or pushed SHA.
2. Fetch checks, reviews, top-level comments, and GraphQL review threads.
3. Separate new actionable feedback from resolved, outdated, informational, duplicate, or bot-noise comments.
4. If the head changed outside this workflow, inspect the new diff before relying on prior conclusions.

Address actionable feedback

1. Verify every new claim against the codebase, API schema, and existing behavior. Do not follow automated feedback blindly.
2. Reproduce a valid defect and add or update a focused test before changing behavior.
3. Implement the smallest coherent fix, run the focused check, commit, and push.
4. Reply to and resolve only the threads fully addressed by that push.
5. Re-fetch the PR after pushing and confirm the live head, checks, and thread state.
