fix: add PyTorch fix scripts and make torch import optional

- Add fix_pytorch.bat for Windows users to repair PyTorch installation
- Add verify_vision.py to check and auto-fix vision dependencies
- Make torch import optional in game_vision_ai.py to prevent crashes
- Provides graceful fallback if PyTorch fails to load
