"""Plan + preprocess the nnU-Net dataset (always --clean), then write the
subject-level splits_final.json: val = split_val cases, train = the rest
(all base + pseudo cases), same 5-fold content so -f 0 is the one we use.
Usage: python scripts_nnu/02_nnu_plan_preprocess.py --val data/manifests/split_val.jsonl [--npp 8]
