fix: Add missing dependencies and fix type mismatch

BUGS FIXED:
1. Missing dependencies in requirements.txt:
   - Added pytesseract>=0.3.10 (OCR service needs it)
   - Added psutil>=5.9.0 (Analytics plugin needs it)
   - Added pywin32>=306 for Windows (window/screenshot needs it)

2. Type mismatch in plugin_api.py:
   - get_eu_window() documented as returning Dict[str, Any]
   - But actually returned WindowInfo dataclass
   - Fixed: Now converts WindowInfo to dict before returning

This should resolve most import and type errors users were seeing.
