feat(status): `adjust` topic — "on"/"off" as window-adjust mode comes and goes

Pushed from refresh_adjust_held and set_mode, so it follows
window_adjust_active() exactly (overview, or Super held, injected or
real). The desktop grid subscribes to show resize handles on its pinned
images in step with the windows' handles: it never holds keyboard
focus, so it cannot read the modifier state for itself.
