Subject: [PATCH] fix(monitor): detect stranded outputs with no active scanout
 in omarchy-hyprland-monitor-modeless

'omarchy-hyprland-monitor-modeless' only checked whether an enabled monitor
had .width == 0 or .height == 0. When an output drops link during an atomic
commit (or loses its CRTC after DPMS off), it retains a valid mode in
'hyprctl monitors all' but is unassigned and absent from active scanout
('hyprctl monitors'), causing the recovery loop in 'monitor-watch' to abort
prematurely and leave the screen black.

Compare active scanout outputs with all connected outputs to detect
unassigned/stranded enabled monitors alongside 0x0 mode monitors.

Fixes #9078
