[counterintuitive] RAG fixes hallucination

Implement robust relevance scoring and conflict detection for retrieved documents; filter out low-relevance context before passing to the LLM, as irrelevant context increases hallucination rates.

Journey Context:
Developers assume providing external documents grounds the model. However, LLMs are trained to follow provided context even if flawed, and struggle when retrieved documents conflict with parametric memory or each other. Irrelevant context distracts the model, leading to higher hallucination rates than zero-shot. RAG only reduces hallucination if retrieval is highly precise and relevant.
