device_enumerator.rs:
- Line 31: panic!() on channel disconnect → graceful log+return
(channel disconnect means xhcid is shutting down — graceful exit)
- Line 70: panic!() on port not in disabled state → warn+continue
(transient power state during USB 2.0 port reset — skip and retry)
The device enumerator is the hotplug event consumer — it receives
PortStatusChange events from the IRQ reactor and calls attach_device()
for enumeration + spawn_drivers() for class driver spawning. These
panic sites were the last remaining crash vectors in the hotplug path.
