The rofi-file-browser-extended navigate-a-tree model felt worse than flat fuzzy-find for a quick launcher (yazi already covers real browsing), so `files` goes back to `fd` → `rofi -dmenu` → xdg-open. calc (rofi-calc) and emoji (rofi-emoji) stay. Re-adds `fd` to the module's packages and notes the dropped plugin in the roadmap. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
