fix: address macOS deployment target and pyzmq compilation issues

- Set MACOSX_DEPLOYMENT_TARGET=11.0 for macOS builds
- Add pyzmq to test requirements to use pre-built wheels
- Configure deployment target in both workflow and pyproject.toml
- Skip ARM64 tests on GitHub Actions to avoid cross-compilation issues
