[counterintuitive] RAG fixes hallucination

Implement a verification step where the agent cross-references the generated answer against the retrieved context, rather than assuming the context alone prevents fabrication.

Journey Context:
Developers assume that providing documents via RAG forces the model to use them, eliminating hallucinations. In reality, LLMs suffer from attention dilution and can still generate answers that contradict the provided context, or invent details not supported by the retrieved chunks. RAG merely shifts the failure mode from ungrounded hallucination to grounded contradiction or context ignoring, requiring explicit verification.
