Subject: [RFC PATCH 2/3] tmon: Add support for THERMAL_TRIP_PLUG type

Extend tmon to handle the new THERMAL_TRIP_PLUG trip type:

- Update UI legend to show 'G=Plug' in status display
- Map trip type to 'G' character in trip_type_to_char()

Align tmon with kernel thermal framework extensions that support
CPU hotplug-based cooling through dedicated trip points.
