Subject: [PATCH] fix(ci): add concurrency to pr-automation workflow

- Add workflow-level concurrency group per PR number
- Enable cancel-in-progress to cancel old runs when new commits arrive
- Prevents multiple pr-automation runs for the same PR from wasting Runner resources

Issue: Same PR could trigger multiple auto-approve/auto-merge runs simultaneously,
occupying ci-check runners unnecessarily. With concurrency, only the latest run
executes, and older runs are cancelled automatically.
