gauges: reconstruct + register the first BT gauge widget (cmHeat) [widget recon 1]

Browse Source 
Begins the BT gauge WIDGET reconstruction -- making the cockpit instruments show
live data instead of just frame art. The BT gauge method table
(BTL4MethodDescription[]) was a chain-only stub with zero registered
methodDescriptions, so every BT-specific gauge keyword was parse-skipped.

Registers the first widget, cmHeat (ColorMapperHeat -- tints the heat/critical
schematic palette by a named subsystem's live temperature):
- Added ColorMapperHeat::methodDescription (keyword "cmHeat", param list
  R,Md,C,St,St,St matching the binary .data) and registered it in
  BTL4MethodDescription[] (chain link stays last).
- Rewired ColorMapperHeat::Make to read methodDescription.parameterList[]
  (the interpreter restores each instance's parsed params there) instead of the
  earlier unrecovered DAT_* placeholders -- so it uses the real CFG rate/mode/
  colour-slot/palette/subsystem-name, and the runtime port arg as the graphics
  port.

Registering it exposed the /FORCE trap: two REAL functions in the chain were
undefined (silently stubbed -> would AV once the gauge builds). Reconstructed
both from the decomp:
- ColorMapper::BecameActive (@004c395c): invalidate the cached colour index +
  last-written RGB so the next Execute re-pushes the hardware palette.
- ColorMapperHeat::~ColorMapperHeat: empty -- the base chain (~ColorMapper ->
  ~Gauge) releases the HeatConnection + palettes.

Verified: register->parse->Make->ctor->FindSubsystem("GeneratorA") (resolves,
no "does not exist")->HeatConnection->Execute->palette-push runs end-to-end
under BT_DEV_GAUGES; no parse desync; combat un-regressed (TARGET DESTROYED,
0 crashes). Establishes the registration recipe + the /FORCE-check discipline
for every remaining widget. Details + priority order: docs/GAUGE_COMPOSITE.md.
