deploy: alias Dockerfile.hf to Dockerfile for HF Spaces auto-discover

Hugging Face Spaces (Docker SDK) requires the build entry point at
./Dockerfile by convention. This is a literal copy of Dockerfile.hf
so the existing tests/deploy/test_dockerfile_hf.py contract still
inspects the canonical Dockerfile.hf source.
