"""Publish captured ScrubData agent traces to a Hugging Face Hub dataset.

Earns the "Sharing is Caring / Open trace" bonus quest. Run after you've exercised
the app (so data/traces/scrubdata-traces.jsonl has records).

    huggingface-cli login                 # one-time (needs HF_TOKEN with write)
    uv run scripts/publish_traces.py      # uploads to build-small-hackathon/scrubdata-traces

The default repo is under the hackathon org; override with --repo for your own.
