Add GitHub Actions auto-sync to Hugging Face Space

On every push to main, mirror the repo to the HF Space so the live app
redeploys automatically. HF write token stored as the HF_TOKEN repo secret.
Move the Space's Docker/app_port config into the shared README frontmatter so
the mirror keeps the Space configured.
