P7: byte-exact re-base of the CORE heat leaf (HeatSink/Condenser/Reservoir/Generator/Myomers)

The reconstruction modeled the binary's shared alarm/connection types with undersized
stand-ins, sliding every field above them low (the 72-byte auxScreenNumber gap). Fix the
foundational heat-leaf classes byte-exact + static_assert-lock them, from the ctor decomp:

Shared types corrected:
  * SubsystemConnection 4 -> 0xC  (binary link node FUN_004af9cf; FUN_00417ab4 derefs +8)
  * GaugeAlarm54 = 0x54           (real AlarmIndicator FUN_0041b9ec; STATUS level at +0x14,
                                   so subsystem+0x184 == heatAlarm+0x14 == GetLevel())
    WatcherGaugeAlarm now typedefs GaugeAlarm54 (Watcher branch locks stay valid).

Byte-exact + locked (ctor-verified):
  * HeatSink   heatEnergy@0x158 linkedSinks@0x164 heatAlarm@0x170 resource@0x1C4
               pendingHeat@0x1C8, sizeof 0x1D0  (@004adda0)
  * Condenser  valveState@0x1D0 condenserAlarm@0x1DC  (@004ae568)
  * Reservoir  reservoirAlarm@0x1D0 ... squirtEfficiency@0x22C, sizeof 0x230  (@4aef78)
  * Generator  stateAlarm@0x1FC, sizeof 0x250  (@004b225c)
  * Myomers    phantom moverConnection tail removed (fits 0x358)

Three systemic bug classes fixed (added to the checklist in CLAUDE.md / HARD_PROBLEMS.md):
  * alias field    - a subclass member re-declaring an inherited slot the ctor reuses
                     (Condenser refrigerationOutput==massScale@0x160; Reservoir
                     coolantCapacity==thermalCapacity@0x128) -> use the inherited name
  * alarm-interior - a value read at alarm+0x14 modeled as a separate member
                     (HeatSink heatState@0x184, Reservoir injectActive@0x1e4)
                     -> route to alarm.GetLevel()
  * phantom field  - a member past the object end (Generator shortFlag@0x25C is really
                     *(owner+0x190)+0x25c the msg-manager, @004b0efc; Myomers
                     moverConnection@0x110 a write-only base slot) -> remove it

Heat conduction now reads the REAL heatEnergy=1.34e7 (not garbage); combat DESTROYED-in-8,
0 crashes, heapcheck-clean through construction.

REMAINING (measured; a distinct larger task): making PoweredSubsystem byte-exact grows it
+0x98 and cascades into MechWeapon/Emitter/PPC/Sensor/Myomers -- all model the 0x54
AlarmIndicator with 4-byte ReconAlarm / 8-byte HeatAlarm stand-ins and are short +
phantom-tailed; retyping without byte-exacting them overflows the Emitter alloc (heap
corruption). PoweredSubsystem kept on HeatAlarm(8) stand-ins (marked) pending a
subsystem-tree ALARM UNIFICATION. See docs/HARD_PROBLEMS.md P7.
