Pepijn dbe01b0444 fix(profiling): fix pi0 cuBLAS error and pi05 OOM on 22GB GPU
- Move cudnn_deterministic to per-spec train_args instead of hardcoding
  it for all models. cuBLAS deterministic mode triggers internal errors
  on Gemma-based models (pi0, pi05) during backward pass.
- Enable use_amp=true for pi0, pi0_fast, and pi05 to reduce memory
  footprint from fp32 (~16GB weights alone) to bf16, fitting within
  22GB GPU budget with room for activations and gradients.
- Small models (act, diffusion, multi_task_dit) still use deterministic
  mode for reproducible profiling results.
