Note

Low Risk
Low risk CI/config-only changes: adjusts a GitHub Actions workflow, bumps lockfile dependency versions for an audit fix, and tightens test coverage thresholds.

Overview
Adds debouncing to the check-pr-required-checklist GitHub Actions job via concurrency (per-PR group with cancel-in-progress) plus a short delay to avoid repeated failures while editing PR descriptions.

Applies an audit-driven dependency update in package-lock.json (protobufjs-related versions) and slightly increases Vitest coverage thresholds (statements and branches).
