Logs each SubsystemCluster::Execute's drawn CurrentTemperature vs the degradation/ failure thresholds + drawState. Confirmed (BT_DEV_GAUGES + madcat + autofire): the per-subsystem temperature bars build lazily on the engineering MFD screen, execute live with animating values (weapons heat toward the 1000K degradation line = the jam threshold) and correct 1000/2000 markers, drawState=0 online. No behavior change (env). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
