[counterintuitive] RAG fixes hallucination

Implement robust chunking, re-ranking, and explicit 'answer strictly from the provided context' prompting with a fallback to 'I don't know', rather than assuming retrieval alone prevents hallucination.

Journey Context:
RAG actually introduces new hallucination vectors. If the retrieved context contains conflicting information, is irrelevant to the specific nuance of the query, or is too noisy, the model will confidently hallucinate based on that noise. Models also suffer from 'attention misdirection' where they latch onto a retrieved but irrelevant entity and invent a story around it.
