feat: add HuggingFace storage channel support

- Add HuggingFace API wrapper class (huggingfaceAPI.js)
- Support upload, download, delete operations via HuggingFace Hub API
- Support public repos (unlimited storage) and private repos (100GB limit)
- Private repos: server proxies requests with Authorization header
- Auto-create repo if not exists (with write token)
- Add HuggingFace to auto-retry channel list
- Environment variables: HF_TOKEN, HF_REPO, HF_PRIVATE
- Support load balancing for multiple HuggingFace channels
