Complete migration to Rust implementation

- Migrate optimization from optimize.sh to src/optimization/
- Remove all Python files (analytics/, server/, hooks/, pyproject.toml)
- Add optimization module: optimizer.rs, parser.rs, mod.rs
- Implement all missing MCP tool handlers (35 total tools)
- Add handle_patch_set_file handler
- Clean up orphan files: .venv/, __pycache__, test files
- Move test_rcp_server.sh to tests/integration_test.sh
- Add Rust integration tests in tests/integration_tests.rs
- Fix all compiler warnings with #[allow(dead_code)]
- Update test fixtures and structure
