[counterintuitive] RAG fixes hallucination

Implement retrieval evaluation, chunking optimization, and citation verification; treat RAG as context localization, not a hallucination cure.

Journey Context:
It is widely believed that providing external documents via RAG stops models from making things up. In reality, RAG merely shifts the failure mode. Models can still hallucinate by ignoring the retrieved context, contradicting it, or 'hallucinating' that the retrieved text says something it doesn't \(unfaithful generation\). Furthermore, irrelevant retrieved context increases hallucination rates due to distraction.
