This commit addresses critical Windows dependency installation issues that were preventing proper application startup:

Fixed Issues:

  • NLTK BadZipFile error caused by corrupted data files in Windows AppData
  • Ultralytics/YOLO settings corruption preventing composition metrics
  • Windows PowerShell execution policy warnings during installation

Changes Made:

  • Cleared corrupted NLTK data cache (C:\Users\AppData\Roaming\nltk_data)
  • Resolved Ultralytics settings.json corruption (auto-recreation)
  • Enabled automatic YOLO model download (yolov8n.pt)
  • Improved Windows installation script error handling

Verification:

  • txt2img server now starts successfully without BadZipFile errors
  • NLTK imports work correctly with fresh data downloads
  • YOLO/Ultralytics composition metrics functional
  • All backend services operational on Windows

Impact:

  • Windows users can now install dependencies without manual NLTK fixes
  • Automatic model downloads work as intended
  • Improved Windows development experience
  • Better error recovery and graceful degradation

Tested on: Windows 10/11 with Python 3.13.3
Fixes: Windows dependency installation failures
