Add the packages a general desktop is expected to ship, chosen to stay
opinionated but average-user friendly:
- Editors: neovim (+ ripgrep, fd for a usable nvim/fzf experience)
- GUI basics: gnome-text-editor, gnome-calculator, file-roller, loupe
- Media: vlc (BOS had codecs but no player)
- Hardware: cups + cups-pk-helper + system-config-printer (enable
cups.socket in post-install), blueman, seahorse
- Platform: qt5-wayland + qt6-wayland (native Wayland for Qt apps under
the QT_QPA_PLATFORM=wayland we set), xdg-desktop-portal-gtk (file
dialogs/screenshare for Flatpak/Electron/Zen), flatpak
