Remove the models folder from the repository ?

### Feature Idea

Could it be possible to remove the models folder from the repository ?
In my setup, I removed the models folder and replaced it for a symlink pointing to another folder. That way, I can have multiple comfyui installs with the same models folder, for example.
But it has a disadvantage: when I update comfy, I need to rename my symlink and recreate the models folder, otherwise the update fails (using comfyui-manager). I suspect this is because it detects a conflict between my local install and the repository.

So, could it be possible to simply remove the models folder from the repository and have it being created programmatically by comfyui upon startup if the path doesn't exists ?

No files or tests are named. Start by tracing ComfyUI's startup path handling and how ComfyUI-Manager detects repository conflicts during updates; done means a missing models path is created automatically and a symlink to a shared models folder remains usable across updates.
