Bound the hybrid GPU gate's supergfxctl query (#6799)

omarchy-hw-hybrid-gpu gates the Hybrid GPU menu entry, and it queried
supergfxctl unbounded — a wedged supergfxd stalled menu rendering
forever. Bound the query with the same TERM-then-KILL escalation the
toggle uses, and treat a daemon that cannot answer like a machine
without supergfxctl: fall back to counting GPUs rather than hiding
hardware that is really there. An ordinary supergfxctl failure still
hides the entry.
