epic: Built-in Model Library

[dan-homebrew]

Model Library

• [ ] Work with eng team to update URLs
• [ ] Update READMEs
• [ ] Provide more quantizations (e.g. full llama.cpp quantizations)
• [ ] Document how to create/add a Model Library
• [x] https://github.com/janhq/cortex.so/issues/78
• [ ] [TBD] Shift Built-in model repos back to Jan's huggingface (better brand recognition, we are also not pushing Cortex as a brand for now)

Models

• [ ] https://github.com/janhq/models/issues/17
• [ ] https://github.com/janhq/models/issues/16
• [ ] https://github.com/janhq/models/issues/19
• [x] https://github.com/janhq/models/issues/26

We will likely need to go over all models, and create a main branch (ie default download)
