Ratified in the loader-key sync: the namespaced locator buys nothing
today (hash/ID-based locating is the long-term direction), and keeping
it adds a third path-shaped field for clients to confuse. loader_path
and display_name carry the loader and display concerns; the storage-root
matching stays internal, still powering display_name.
Response-surface only; no column or migration involved.
Split the Asset response path fields so model-loader consumers get a
category-relative path. The namespaced storage locator moves to
`logical_path`; the new `file_path` is the in-root loader path (model
category dropped), e.g. models/checkpoints/foo/bar.safetensors -> foo/bar.safetensors.
Buckets sharing a base directory (e.g. diffusion_models and a custom
unet_gguf) tagged every file in the directory regardless of whether the
bucket could load it, so .safetensors files were tagged
model_type:unet_gguf and vice versa. Carry each bucket's registered
extension set through get_comfy_models_folders and only emit a
model_type tag when the file extension matches, keeping the empty-set
match-all convention from folder_paths.filter_files_extensions.
Files under a model base matching no bucket now keep only the models
tag instead of every directory-matching model_type tag.
