Fix for exo

[rabejens]

When using the OpenAI compatible endpoint of Exo, getting v1/models will not expose the model list at data but rather return it directly:

$ curl http://192.168.10.118:52415/v1/models

This led to an error when retrieving the model list because res.data was undefined in app/utils/constants.ts line 323.

My quick fix checks if res.data is there and uses it, otherwise, it uses res directly.

I also added a Nix flake and direnv configuration for people using Nix (Darwin or OS) with direnv to manage their development environments.

could you add exo as a provider
