make_colab_zip.py now accepts --mode pretrain|finetune (default: pretrain).
Finetune mode bundles scripts/train.py + data/processed/user/{train,val}/*.pt
plus an optional --include-checkpoint flag for pretrained.pt.
notebooks/colab_finetune.ipynb covers the full Colab fine-tuning workflow:
upload zip → upload pretrained.pt → verify data → train → inspect → download.
