feat: cortex pull FILEPATH

[freelerobot]

Problem
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

1. Tools make me download models from scratch
2. I already have these models and my internet is slow
3. Sad times ensue

Success Criteria
A clear and concise description of what you want to happen.

1. Users can pull models directly from a local filepath
2. A model.yaml is autogenerated, or user selects from preset with ability to edit (this step is likely similar to users downloading a model from a random HF organization)
