- Add device utilities (get_device, get_amp_dtype, get_autocast_device_type, is_memory_query_supported) - Enable MPS device detection and device-agnostic autocast/AMP - Update all inference scripts to use auto device selection (CUDA > MPS > CPU) - Update Gradio app and data processing scripts for MPS compatibility - Add memory-safe cache clearing for CUDA-only operations

Summary
Add MPS (Metal Performance Shaders) inference support for Apple Silicon Macs.
