"""Deploy the current working tree to the Hugging Face Space.

The Space (https://huggingface.co/spaces/lefft/contimp-app) builds from its own
copy of these files. This uploads the repo's working tree to the Space, which
triggers a rebuild. Merging to GitHub does NOT deploy — this is the deploy step.

Run after merging a change to main, from anywhere in the repo:

    uv run --with huggingface_hub python scripts/deploy.py -m "what changed"

Auth: uses your cached Hugging Face login (run `hf auth login` once; token lives
in ~/.cache/huggingface/). You must have write access to the Space. No app
secrets are involved here — those live in the Space's own Settings, never in
this repo. `.env` and other local-only files are excluded from the upload.
