Add enhanced batch file with optional dependency checking

Browse Source 
Enhanced run_comfyui.bat with:
- Automatic detection of missing critical dependencies
- Virtual environment detection and warnings
- Optional user-prompted installation with clear warnings
- Comprehensive dependency checking for all essential packages

NOTE: Author is not a professional coder and relied heavily on Cursor AI for implementation. Please review code thoroughly before merging.
