Find models and be able to change models without going into the settings

[trymeouteh]

For Privy to find the installed models when using Ollama or another provider and be able to change what model to use in the chat window without going into the settings to change the model to use.

I think a better approach is to have in the Privy setting to select a default model which will be used everytime you launch VSCode. Then in the chat window, you can change the model used when creating new chat window
