Initial commit: wallhaven-dl wallpaper browser and downloaderHEADmaster

Single-file PyQt6 app for wallhaven.cc:

- search with purity tabs, category checkboxes, per-monitor size filter
  and a color swatch row; all filters sent explicitly so account
  preferences never leak into keyed searches
- thumbnail grid with a downloaded overlay, preview panel with full
  image, details and download
- API key from pass, sent only to the API in the X-API-Key header
- client-side rate limiter (40/min) with a status bar meter, and a
  debounce on filter changes
- library-wide duplicate detection by wallhaven id under
  ~/Pictures/wallpapers
- low-res finder: flags images smaller than their monitor and searches
  replacements by first tag or by locally extracted dominant color,
  with a floating reference window and replace-to-trash
- desktop entry and Candy-style icon
