feat: fetch AUR descriptions and categories in generate-index.py

- Fetch description/URL/license/depends from AUR API for packages
  without local PKGBUILD (AUR-only packages like kwin-zones, etc.)
- Add keyword/description-based category fallback so unknown packages
  aren't all 'other' — maps keywords like 'kwin' → desktop,
  'aur/helper/pacman' → tool, 'icon-theme' → branding, etc.
- Keep explicit category rules for known packages
