Complete FTPO training run; document orchestration bug fix and thermal shutdown
Ran the full FTPO fine-tune to completion: 4h12m wall-clock, early-stopped at step 380/750 by the configured chosen_win=0.85 threshold, train_loss 4.0->2.19. Output is a merged 16-bit model plus LoRA adapter. Also fixes an UnboundLocalError in core/orchestration.py when resuming a run with generation disabled (--generation-step-enabled false), which is needed to re-run just the finetune stage against an already-generated dataset. Documents an unrelated platform incident: an uncapped multi-hour finetune triggered a thermal shutdown mid-run with no checkpoint saved, requiring a restart from step 0. Capping GPU clocks/power before the retry let it complete without issue.
