Fix: Add HF_HOME and disable XET to fix permission denied error

ROOT CAUSE:
- XET logging tried to write to /home/user/.cache/huggingface/xet/logs/ (read-only)
- Setting cache_dir in Python code didn't affect XET's logging location

SOLUTION:
- Set HF_HOME=/data/.huggingface in YAML env section
- Disable XET entirely with HF_HUB_DISABLE_XET=1
- This ensures all HuggingFace components use writable /data directory
