update longcat-video-avatar-1.5 to model libraries

Note

Low Risk
Single registry entry with no runtime or security-sensitive logic changes.

Overview
Registers LongCat-Video-Avatar-1.5 as a Hub modeling library in MODEL_LIBRARIES_UI_ELEMENTS, keyed by longcat-video-avatar-1.5 (matching library_name on models).

The entry points to the LongCat-Video repo, keeps the library off the main models filter (filter: false), and defines download counting via .safetensors files or config.json.

Suggested change

	"longcat-video-avatar-1.5": {
	prettyLabel: "LongCat-Video-Avatar-1.5",
	repoName: "LongCat-Video-Avatar-1.5",
	"longcat-video": {
	prettyLabel: "LongCat-Video",
	repoName: "LongCat-Video",

Only a suggestion but I feel that since the library is named LongCat Video (according to https://github.com/meituan-longcat/LongCat-Video), then the tag should be this instead of the exact repo name itself. This is only a suggestion, if you prefer longcat-video-avatar or even longcat-video-avatar-1.5 then go for it (though I find them too long/specific). The important part is that you had

library_name: longcat-video

in the model card metadata of the model.

Since it's a diffusers model, you can also do

library_name: diffusers
tags:
  - longcat-video

or

# preferred version if you want longcat video download count rule
library_name: longcat-video
tags:
  - diffusers

In both cases, both libraries will be detected but the library_name one will be considered as the "main library" which we will use to count download.

Counting both safetensors and config files will lead to double-counting download if someone downloads the full repo. The best in this situation is to only count by config.json, which is the default rule. So my advice here is to remove this line and fallback to the default rule

Suggested change

countDownloads: `path_extension:"safetensors" OR path:"config.json"`,
