Heat: THE AUTHENTIC ELECTRICAL MODEL -- weapons recharge from generators (task #10)

Task #10 set out to fix "scrambled linked-sink routing"; a [heat-link] attach
log proved the routing was NEVER scrambled (every subsystem links its authored
condenser exactly; the "pools in Condenser1" read was the diagnostic-sampler
aliasing trap).  The real defect: emitter.cpp's local FUN_00417ab4 stub
returned NULL, so the whole electrical model was inert and the E7 force-charge
recharged every emitter in ONE frame (~0.3s cycle, 1501 fires/90s, ~1.7e9
heat/s -- the "runaway").

Landed authentically [T1: disasm + byte-verified constants]:
- Emitter ctor @004bb120: seekVoltage = authored fraction x generator
  ratedVoltage (10000); EC = energyTotal/(seekV^2 x 0.5); voltageScale@0x310 =
  (RechargeRate / -ln(1 - 1e-4 x seekV)) / EC -- charge reaches seekV[rec] in
  EXACTLY the authored RechargeRate (PPC 5s, ERL 4s, SRM 3s, ERM 2s) cold.
  Owner-flags ctor gate (the usual gotcha; the this-flags read never armed).
- PoweredSubsystem::ChargeTimeScale (@004b0d50, was a =1.0 stub): voltageScale
  x (1 + thermalResistivity x srcTempRise) -- hot generators charge slower.
  ("voltageScale is never read back" was wrong; corrected + swept.)
- TrackSeekVoltage @004ba838: charging I^2R -> the GENERATOR's pendingHeat
  (~3.5e8/full PPC charge) -- generators self-heat, conduct to their authored
  condensers, and throttle further charging.  The feedback economy closes.
- FailureHeat consumers found: this+0x184 == 2 gates BOTH weapon families
  (@004baa88 emitter: reset firing + hold charge 0; @004bbd36 ballistic:
  recoil=rechargeRate + alarm 7).  Emitter::GetFaultState un-stubbed.
- ProjectileWeaponSimulation @004bbd04 opens with call 0x4b0bd0 (disasm) --
  launchers now run the powered/heat step (their firing heat previously
  accumulated in pendingHeat forever).
- heat.cpp: per-instance BT_HEAT_LOG census (the old shared-static 1-Hz
  sampler aliased); [heat-link] attach log; the stolen-else Verify restored.

Verified live (120s max-rate autofire): PPC ~470-500 (was 55,000), bank
plateaus ~600 and sheds to ambient, generators 1100-1400, ERMLaser
self-regulates at the authored 2000 failure threshold (shutdown-cool-resume).
