First rag chatbot commit

[samcraftt]

• AI-generated descriptions of the frontend client's files and components and also server_api/main.py serve as the knowledge base for the rag chatbot
• Used FAISS to vectorize these files and they're stored locally (server_api/chatbot/faiss_index)
• Also moved a the function process_path from server_api/main.py to a shared utils.py file since it's now used in two files (the new chatbot.py file)
