"""Upsert data_final entry into LLaMA-Factory/data/dataset_info.json (idempotent).

NOTE: LLaMA-Factory resolves `file_name` relative to `dataset_dir`, so we write
an absolute path resolved at script run time. The script script is expected
to be run from the parent dir of `demo/` (which run_all.sh / 03_train.sh do).
