feat: add -v/--version CLI flag with dynamic version from pyproject.toml

- Add argparse support to main server entry point
- Create get_version() function to read version from pyproject.toml
- Support both tomllib (Python 3.11+) and tomli (Python 3.10)
- Add tomli as conditional dependency for Python < 3.11
- Bump version to 1.2.1
