John Pollock 291a4a4572 feat: Add support for Apple MPS devices
Update the `get_device_list` function to detect and include the 'mps' (Metal Performance Shaders) backend if it's available through PyTorch.

This allows users on Apple Silicon hardware to see and select their GPU for accelerated computations.
