…n3 encoder The Z-Image Qwen3 text encoder requires both text_encoder and tokenizer subfolders from the HuggingFace repo, but the previous implementation only downloaded the text_encoder subfolder, causing model identification to fail. Changes: - Add subfolders property to HFModelSource supporting '+' separated paths - Extend filter_files() and download_urls() to handle multiple subfolders - Update _multifile_download() to preserve subfolder structure - Make Qwen3Encoder probe check both nested and direct config.json paths - Update Qwen3EncoderLoader to handle both directory structures - Change starter model source to text_encoder+tokenizer
