"""Verify the Sensor/Avionics handler-set fix (input-path audit systemic cause #1).

The MFD2 ENG1 page's power bank -- 6 clickable buttons, keys F5-F9 -- sends
message ids 3-8 to subsystem 14 ("Avionics", class Sensor).  Sensor's
MessageHandlerSet was DEFAULT-CONSTRUCTED (entryCount 0, no parent chain), so
Find() returned NullHandler for every id and Receiver::Receive dropped them in
silence: 108 streamed records across the 18 mechs, all dead.  Sensor now chains
PoweredSubsystem::GetMessageHandlers() (ids 4-8) which chains HeatSink (id 3).

PASS  = a [gensel] line naming Avionics after an F-key press.
Also prints any [msg] UNHANDLED pairs the new trace catches.

Kills only the PID it spawns.
