Replaces torch.mps.is_available() with torch.backends.mps.is_available()
across all files. The torch.backends API is the official PyTorch method
for MPS detection (since PyTorch 1.12) and works reliably on:
- macOS with Apple Silicon (returns True when MPS available)
- macOS without MPS support (returns False)
- Windows/Linux (hasattr guard prevents AttributeError)
Add defensive checks for torch.mps.is_available() to handle PyTorch versions where the method doesn't exist on non-Mac platforms. Resolves AttributeError: module 'torch.mps' has no attribute 'is_available'
- Add max_resolution parameter (default: 0 = no limit) to both CLI and ComfyUI
- After new_resolution scales shortest edge, max_resolution ensures no edge exceeds limit
- Scales down proportionally if constraint violated
- Maintains backward compatibility with default value of 0
