Feat/rag url langchain

[jondwillis]

https://github.com/stackwiseai/stackwise/assets/906671/d6765ee7-fac7-4d5e-b41a-ff9d1e1bdd10

some new features:

• [x] uses a langchain RAG agent
• [x] supports rag over multiple urls
• [x] url highlighting in editor
• [x] change the underlying model
• [x] chat history
• [x] streaming agent final output (nextjs app template says this isn't possible, but it is!)

further improvements:

• [ ] streaming agent actions/intermediate steps (too lazy to build this right now)
• [ ] gemini (actually goes out and does work ( try adding LANGCHAIN_VERBOSE="true" to .env), but output is not rendered)
• [ ] smart ingest (on url detected, instead of waiting)

possible issues:

• the puppeteer endpoint has to be nodejs, so I split it out into another API route. therefore the entire backend code won't be copied without more work.

What are the next steps for deploying this?
