branch-cleanup

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The caller workflow uses a git repository reference YOUR-ORG/.github/.github/workflows/reusable-branch-cleanup.yml@REPLACE-WITH-FULL-COMMIT-SHA which GitHub Actions fetches and executes at runtime, so this is a required external workflow that runs remote code.
