mpvpaper kept running over the new theme's static wallpaper because nothing was watching the omarchy-theme symlink. Add a small sibling script that polls ~/.config/omarchy/current/background and, when the target changes, runs `motion-wallpaper-toggle stop` — which tears down mpvpaper and respawns swaybg with the new symlink target so the new theme's bg becomes visible. - motion-wallpaper-theme-watcher: polls readlink every 2s, exits silently on non-Omarchy systems where the symlink doesn't exist. - toggle: spawn alongside the auto-pause watcher; kill alongside it. - wallpaper.sh: install the new binary.
