Mech phase 2: reconstruct HeatWatcher (: MechSubsystem) subsystem

Watches another subsystem's temperature, drives a 3-level alarm. Sibling branch to HeatableSubsystem (derives straight from MechSubsystem). Ctor + statics + dtor + TestClass/TestInstance/ResetToInitialState real; WatchSimulation (per-frame) staged. Unblocks PowerWatcher -> Torso/HUD/Gyroscope. BT: 27 ok.
