idea: `cortex models list` remote & downloaded models

[0xSage]

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

1. Users want to see what models are preconfigured and available via HF/cortexso
2. Users want to see what models are available to be used locally, they've already downloaded

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

Not sure about this:

# List all available models , including remote models on cortexso available for download
cortex models list 

# List models on device only (-l or some other flag)
cortex models --local

Additional context Add any other context or screenshots about the feature request here.

I am deprecating this issue, as Cortex.cpp should not be handling remote model (this is a Jan Extension concern)
