[counterintuitive] RAG fixes hallucination

Implement RAG with strict citation enforcement and hybrid search; do not assume retrieved context eliminates hallucinations, as models will hallucinate \*about\* the retrieved context.

Journey Context:
The consensus is that giving the model the right data stops it from making things up. In reality, RAG introduces new failure modes: the model can conflate multiple retrieved chunks, fail to distinguish between similar entities in the context, or blindly agree with a retrieved document even if it contradicts its pre-training. RAG shifts the failure mode from fabrication to context-confabulation, which is harder to detect because the output sounds authoritative and grounded in the provided text.
