## Summary

- Re-triggers CI after Claude Code pushes commits by closing and
reopening the PR (workaround for GITHUB_TOKEN commits not triggering
workflows)
- Updates pr-fix command to post a summary comment on the PR when done,
with collapsible details

## Background

When Claude Code pushes commits using `GITHUB_TOKEN`, GitHub's
anti-recursion protection prevents other workflows from triggering. This
PR adds a step to close and reopen the PR after Claude pushes, which
triggers the `reopened` event that CI listens for.

Also adds instructions to the pr-fix command to have Claude post a
summary comment on the PR summarizing what was done.

## Test plan

- [ ] Verify CI re-triggers after Claude Code pushes commits
- [ ] Verify summary comment is posted on the PR

## Summary by cubic
Automatically re-triggers CI after Claude Code pushes and adds a clear
PR summary comment when pr-fix completes. This avoids missed builds from
GITHUB_TOKEN commits and helps reviewers see what changed.

- **New Features**
- Detects new commits from Claude and re-triggers CI by
closing/reopening the PR (uses HEAD tracking, GitHub API, and a reopen
retry for reliability).
- pr-fix posts a success/failure summary comment with addressed review
items, CI fixes, remaining issues, collapsible details, plus a workflow
run link; handles comment failures and missing env vars gracefully.

<sup>Written for commit 77be40a076e264333efb046a81fbc6920b5adc64.
Summary will update on new commits.</sup>
