fix: Pin Ruff version to 0.12.2 for consistency

- Pin ruff==0.12.2 in pyproject.toml dev dependencies
- Update uv.lock to use exact version
- Ensure local and CI environments use identical Ruff version
- Prevents version drift causing different linting behavior

This ensures both local development and GitHub CI use the same Ruff rules and behavior.
