The quickshell pilot proved out in daily use; promote it from manual
pilot to the session default. Additive — no hard deletes: Waybar and
swaync stay installed as reserves.
- niri spawns `quickshell` instead of `moonarch-waybar`; Alt+W toggles
quickshell ⇄ Waybar for the rare fallback
- swaync's spawn-at-startup is commented out so it releases
org.freedesktop.Notifications for quickshell's own server (verified:
quickshell owns the name; flip the comment to return to swaync)
- quickshell added to packages/official.txt (config ships automatically
via moonarch-git's defaults/xdg install loop)
Remaining: push → CI rebuilds moonarch-git → pacman -Syu; niri changes
take effect on relogin.
