ci: add Claude PR review, drop @claude mention handler

[ak-bugsee]

Adds a caller for the shared review workflow in bugsee/.github and removes the per-repo claude.yml @claude mention handler.

Opening this PR also triggers the first review run, so it doubles as a check that the setup works.

📝 Summary

Summary by CodeRabbit

• New Features
  • Automated reviews run when a pull request is opened, updated, marked ready for review, reopened, or labeled.
• Changes
  • Claude Code can no longer be triggered by mentioning @claude in issues or pull request comments and reviews. Automated reviews are now associated with pull request events rather than being triggered by those mentions.

The repository adds a GitHub Actions workflow for pull request events. It calls the reusable Claude review workflow with specified permissions and passes the Claude OAuth token secret. The existing workflow that ran Claude Code in response to @claude mentions and related issue or review events is removed.

Priority: ⬇️ Low

Change: Other

Merge Risk: ⚪ Minimal · up to f7cf8

The workflow runs reviews on the configured pull-request events, while unrelated labels do not invoke Claude. No actionable merge-blocking risk remains.

### Architecture Summary

Architecture risk: 🔵 Low · up to f7cf8

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.
