ci: cancel claude rebase when PR closes (#2915)

## Summary - trigger the Claude rebase workflow on PR close events - add a per-PR concurrency group so a close/merge event cancels any in-progress rebase run - restrict the rebase job itself to labeled events so closed PRs only trigger cancellation ## Test plan - npm run fmt - npm run lint:fix - npm run ts - npm test #skip-bugbot 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2915" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>
