Describe the solution you'd like

1. Consolidate linting/fixing workflow definitions to avoid config drift between Hatch scripts, pre-commit hooks, and GitHub Actions.
2. Add automated dependency/security update and vulnerability scanning (Dependabot + pip-audit/OSV scan in CI).
   3 Rebalance CI matrix strategy (smoke vs full matrix) to reduce turnaround time while preserving cross-platform confidence.
