(feat) Circles Chatbot "Cayman"

[matthew-lim-matthew-lim]

TODO:

MVP:

• Write per-user rate limiter to prevent spamming
  -> If guest users is implemented in the future, this must be implemented for them.
• Improve Chatbot intelligence: What context do we give it?
• Improve Chatbot intelligence: Prompt engineering
• Improve Chatbot intelligence: What tools do we give it?
• UX/Testing: What questions from the user should we use to test Cayman? It can do so much, but what do we want to guarantee to work for users?
• Clean code

Extended:

• Add Unilectives API tool so it can make requests to Unilectives API
• Add web search or something to get sentiments about the course from other people (maybe reddit for example)
