Heat: authentic 1e7-unit heat + the ambient radiator land (task #9)

- Emitters: heatPortion closed form = heatCostToFire x 1e7 x (charge/seekV)^2
  (PPC 1.1e8 -> +632K on its own sink); the missing projectile/missile heat
  adds (raw -- resources author pre-scaled 1e7 units).
- The bank's AMBIENT RADIATOR @4ae73c reconstructed (the system's ONLY heat
  exit; conductance x 0.1 x HeatSinkCount -- _DAT_004ae974 float80 = 0.1) +
  the link-attach guard corrected (skip = the 0xBBE bank, not Condenser; the
  inversion blocked condenser->bank links and closed the system).
- Constant corrections (all byte-verified float80s): coolant epsilons
  0.0025/0.003/1e-4 (was a single 1e-4 serving three sites);
  CoolantCapacityScale 0.05 (was 1.738).
- Verified: heat flows + exits; max-rate autofire overheats weapons into the
  authentic heatLoad range-cutout (thermal spam unsustainable by design).
- KNOWN REMAINING: linked-sink routing scrambled (heat pools in Condenser1;
  authored map says PPC->C4/C6) -- the heat-stream offset audit, filed.
