Merge Risk: 🟡 Moderate · up to A pull request with newly pushed changes can still be closed while GitHub is computing its diff. This defeats the intended race protection and should be corrected before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@pkg/plugins/scms/github/pullrequest.go`:
- Around line 323-408: Update isPullRequestEmpty so a matching head commit does
not immediately trust ChangedFiles; re-query the pull request state and require
the matching-head diff result to be settled before returning true. Ensure a
refreshed p.remotePullRequest with zero ChangedFiles after a push cannot cause
CleanAction to close a pull request containing changes, while preserving the
existing retry and skip-cleanup behavior.
