Note

Low Risk
Dependency-only update that changes the pinned verifiers git revision; risk is limited to potential behavioral changes introduced upstream.

Overview
Updates the pinned verifiers dependency to a newer git revision (9052ecf → 3f555af) in both pyproject.toml and uv.lock, ensuring builds resolve to the new upstream code and lock metadata.
