Add Model Fetcher (comfyui-modelfetcher)

[KoLt-Real]

Adds Model Fetcher, already published on the Comfy Registry: https://registry.comfy.org/nodes/comfyui-modelfetcher

• Repository: https://github.com/KoLt-Real/ComfyUI-ModelFetcher
• Registers no nodes: a top-bar button that reads the open workflow's Markdown notes, downloads the models they list into the right models/ subfolder (extra_model_paths aware, resume, HuggingFace token kept to HF hosts only), flags likely duplicates, and relinks loader nodes to copies already on disk.
• No dependencies beyond what ComfyUI ships (requests, aiohttp); no build step; comfy node validate passes clean.

[ltdrdata]

This pack exposes network-reachable routes with no access control: one writes files from a caller-supplied job, and a token route writes/clears a credentials file. A url is also fetched with no host allow-list.

• downloader.py:204 (fetch), downloader.py:242,267 (write), hf_token.py:86-94,114 (token write/delete)

Please make these routes local-only, restrict the fetch to a host allow-list, and confine the write path. I'll re-evaluate once constrained.
