feat: optimize gz calculation and expose mesh simplification

- Implement Newton-Raphson solver for faster draft finding.
- Implement mesh simplification using meshopt for faster GZ computation.
- Expose simplify and to_simplified methods to Python.
- Fix Rust clippy warnings and update documentation.
