Could you let me know the reason for using nomic-embed-text as the default embedding model for ollama?

Thank you for sharing this wonderful project!
I have confirmed that embedding is a key factor directly linked to improving Deepwiki's performance and I am currently conducting extensive testing.

Regarding code embedding, since nomic-embed-code is specialized for code embedding, it seems like performance could be further improved.
I'm curious if there's a specific reason you're using nomic-embed-text, which is a text embedding model rather than a code embedding model.

I would appreciate your response!
