Improve context tracking within conversation

[lukehinds]

See note from @dussab

Due to the non deterministic LLM responses, it was difficult to fix the issues one at a time and then rerun the same prompt and get the same response (minus the fixed issue). For example, I wanted to fix the input validation and html injection issues one at a time and reran the "Hey codegate how can i fix "@GetMapping("/hello")" in @DemoApplication.java" after fixing the input validation and i got a completely different recommendation to fix the HTML injection compared with the first attempt.

We might need some type of tracking within the current session, this could perhaps be achieved with rag which is empeheral for that particular chat run.
