Note

Low Risk
Dependency-only update: bumps the verifiers git revision, with risk limited to behavior/performance changes introduced upstream. No application code changes in this PR.

Overview
Updates the verifiers dependency to a newer git revision (de2ed50 → 1960e77) via pyproject.toml and refreshes uv.lock accordingly.

The lockfile changes primarily reflect the new verifiers source pin and associated resolved artifacts/metadata updates.
