feat: auto-reply Add GitHub Actions workflow for CodeRabbit suggestion replies apply on CodeRabbit suggestion comments

[Copilot]

Summary

Automates applying CodeRabbit inline suggestions on PRs. When CodeRabbit posts a review comment containing a suggestion block, the workflow immediately replies @coderabbit apply, triggering CodeRabbit's own apply mechanism — no diff parsing, no file manipulation, no fragility.

Changes

• Add .github/workflows/coderabbit-auto-apply.yml — triggers on pull_request_review_comment: created; guards on user.login == 'coderabbit-ai[bot]' AND body contains ```suggestion; posts reply via pulls.createReplyForReviewComment

Agent Checklist

• npm run test:ci passes (all unit tests green, coverage not decreased)
• npm run build && npm run test:e2e passes (all E2E tests green)
• No generated files committed (script.js, styles.css, *-data.js)
• All dynamic innerHTML values pass through escHtml()
• No DOM references introduced in death-clock-core.js
• No new runtime npm packages added
• GitHub Actions uses: pins use a full commit SHA + inline semver comment
• PR title follows Conventional Commits (feat:, fix:, docs:, chore:, etc.)
• project-stats.yaml updated if this session merges one or more PRs
• Relevant entry added to docs/LEARNINGS.md (new pattern or lesson learned)

Summary by CodeRabbit

• Chores
  • Added a GitHub Actions workflow that listens for new pull request review comments and automatically posts a reply when specific comment criteria are met. This automation replies on the same pull request and comment, streamlining how review-comment replies are created without changing any public APIs or exported code.

Inline comments:
In @.github/workflows/coderabbit-auto-apply.yml:
- Around line 14-15: The condition checking the comment author uses the wrong
bot login string; update the workflow condition that compares
github.event.comment.user.login (and the contains check) to use
'coderabbitai[bot]' instead of 'coderabbit-ai[bot]' so the branch with
contains(github.event.comment.body, '```suggestion') can match and the job will
run.
