Eliminates the ~1.3 GB cold-start download on the first conversion. The
new BAKE_MODELS build-arg defaults to true; pass --build-arg
BAKE_MODELS=false to skip and keep the smaller 1.9 GB image when the
deployment can tolerate a slow first run.
Drop the hf_cache volume from compose — a named-volume mount on top of
the baked path would mask the prefetched models with an empty volume on
first 'docker compose up'. The image is now self-contained.
Measured on arm64:
- latest-local without bake : 1.89 GB
- latest-local WITH bake : 3.19 GB (still -48% vs 6.09 GB baseline)
