Add uv dependency management and dev tooling

- Add dependency-groups for dev and testing in pyproject.toml
- Add mypy and ruff to dev dependencies
- Configure uv to use both groups by default
- Add uv.lock for reproducible environments
- Update .gitignore for uv cache

This enables faster, more reliable dependency management using uv.
