Design for adding HuggingFace Buckets API to the Rust SDK, covering HFBucket handle, API methods, xet integration, error handling improvements, blocking API, and CLI commands matching the Python hf buckets interface.
13-task plan covering error handling, types, HFBucket handle, xet refactoring, API methods, blocking wrapper, and CLI commands.
…ants Extend HFError with dedicated variants for HTTP 403, 409, and 429 status codes, plus BucketNotFound for bucket-specific 404s. Update check_response to map these status codes to the new variants instead of the generic Http error. Remove now-redundant inner status code matching in format_hf_error.
Add impl HFBucket with info, list_tree, get_paths_info, get_file_metadata, batch, delete_files, upload_files, and download_files methods. Xet integration uses bucket-specific token URLs.
