Problem
The macOS wheel builds for the codegen Python package have been failing, preventing new releases from being published to PyPI. The latest version on PyPI is 0.54.1, which is a week old.
Root Cause
The build system uses Cython extensions and requires Rust to be installed. While there's a Linux-specific configuration in cibuildwheel that installs Rust, there was no equivalent configuration for macOS.
Solution
Added a macOS-specific configuration section to the cibuildwheel configuration in pyproject.toml that:
This mirrors the existing Linux configuration and should allow the macOS wheels to build successfully.
Testing
This change should be tested by the CI system when it runs the release workflow.
