* fix: add null check for pr.head.repo in stale PR workflow
When a fork is deleted after a PR is created, pr.head.repo can be null
(documented GitHub API behavior). This would cause a TypeError when
accessing properties like fork, full_name, or clone_url.
Added a null check that fails gracefully with a clear error message
when the source repository has been deleted.
