Feat: Add ollama, mistral ai and others

[Yhozen]

This PR switches from OpenAI node library to vercel AI sdk, which abstract many AI apis.

I think a settings section would be a nice addition + the persistent storage added in #3

I would do it but I honestly suck at frontend :(

Adding more models/providers is trivial now with the ai sdk (think of it like the orm or prisma of AI apis)

This is WIP since there's no way to add/edit/delete keys (or other settings i.e: ollama url) for providers

Hi, that's an excellent improvement to the code! This feature is exactly what I need and am working on right now, and I'm also researching this area.

However, when I tested the code on this branch, I noticed that the AI SDK might conflict with the Cross-Origin Resource Sharing (CORS) policy, resulting in a 403 error. I’m unsure of the exact cause, but it seems related to this issue.

A potential solution could be to request with mode: 'no-cors'. I'm not very familiar with the AI SDK library, so let's work together to figure out this issue :)

Test Platform:

• model: Macbook (M1 pro)
• system: MacOS 14.5 (23F79)
• browser: Chromium Engine Version 126.0.6478.57
• User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36

I will give it a try later today!
