Pin huggingface_hub version to <1.0.0 to avoid import errors with Gradio OAuth

 - To avoid spending GPU time on downloads, click **Download / refresh models** once after each deployment to prefetch weights on CPU.
 - If inference ever needs more time, adjust the `duration` parameter in `app.py`, but keep it as low as practical to respect ZeroGPU queue fairness.
 - A lightweight, bundled `twinbooster` shim (version `0.3.1`) is shipped in `./twinbooster/` to avoid PyPI's Python 3.8 restriction on the official wheels. No external install is required; the public API used by the app is preserved.
+- `huggingface_hub` is pinned to `<1.0.0` because Gradio OAuth still imports `HfFolder`, which was removed in 1.x; keep this constraint to avoid startup import errors on ZeroGPU.
