[counterintuitive] RAG fixes hallucination

Implement retrieval evaluation, re-ranking, and citation verification. RAG shifts the failure mode from 'hallucination due to lack of knowledge' to 'hallucination due to misretrieval or ignored context'.

Journey Context:
Developers assume providing context guarantees the model will use it. In reality, models suffer from 'lost in the middle' \(ignoring context in the middle of the window\), can be distracted by irrelevant retrieved documents, and will still hallucinate if the retrieved context is contradictory. RAG does not fix hallucination; it merely provides an alternative pathway for the model to override its parametric memory, which it may still fail to do.
