Address review feedback: Switch to hatchling, remove pip, use ruff-action

- Switch build backend from setuptools to hatchling for simpler configuration
- Remove all pip support, require uv for installation (10-100x faster)
- Update GitHub Actions to use official ruff-action for better performance
- Remove daily schedule from ruff workflow (wasteful for just linting)
- Clean up ruff exclude configuration using extend-exclude
- Update README.md with proper uv tool commands for installation
- Update Makefile to use uv exclusively
- Update CONTRIBUTING.md to remove pip references
- Keep optional-dependencies instead of dependency-groups (uv doesn't fully support PEP 735 yet)

All changes tested and verified working:
- Build system creates identical wheels/sdists
- All 14 entry points preserved and functional
- Editable installs work correctly
- Ruff configuration simplified and working

Note: funding.json changes are from case sensitivity fix already in master
