The model field now accepts either a manual string or a MODEL connection.
When wired, the model name is extracted from the patcher's
cached_patcher_init (registered by core loaders load_checkpoint_guess_config
and load_diffusion_model, preserved through LoRA clones) and converted to a
ComfyUI-style relative name via config model roots.

- model input declared as "STRING,MODEL" with widgetType STRING, so the
  text widget and the dual-type connection slot coexist; non-STRING/MODEL
  links are rejected by frontend and backend type validation
- UNETLoaderLM GGUF branch now registers a custom cached_patcher_init reload
  factory so GGUF models participate in name extraction and ModelPatcher
  deepclone/dynamic machinery
- shared collect_overwrite_params() helper keeps the node and the metadata
  extractor conversion logic in sync; extraction failures are logged instead
  of silently dropping the overwrite
