PyTorch doesn't publish CUDA builds for macOS. As such, we gate on `platform_system` to instruct uv to ignore
the PyTorch index when resolving for macOS.
PyTorch doesn't publish CUDA builds for macOS. As such, we gate on `platform_system` to instruct uv to use
the PyTorch index on Linux and Windows, but fall back to PyPI on macOS:

```toml
