Address PR Feedback

Handle existing PR feedback through assessment, fixes, validation, push, and reviewer-facing replies. Requires Git and authenticated gh; the optional collector also requires Python 3. PR feedback includes review bodies, issue comments, bot summaries, outside-diff findings, inline threads, and follow-ups.

For dependent PRs, read Stacked PRs before mapping or changing the chain. Feedback handling alone does not authorize retargeting, history rewrites, or merging; use the landing route only when authorized.

Collect and assess

Identify the repository, PR, base/head, author, latest head SHA, and review state. If no PR is named, infer the current branch PR with gh pr view.

Prefer scripts/collect_pr_feedback.py for complete feedback and reaction collection:
