Summary
This updates the trusted invalid-label writer to handle fork pull request workflow runs when GitHub does not populate the run's pull request association.
When the association is absent, the writer now searches using trusted workflow-run metadata and requires exactly one open pull request matching the expected base repository, full head repository, branch, and head SHA. Ambiguous, malformed, or stale matches continue to fail closed.
The existing workflow identity checks, pull request revalidation, label/state checks, write permissions, and scheduled reconciliation fallback remain unchanged.
