[counterintuitive] RAG fixes hallucination

Implement citation verification and context-window grounding checks; treat RAG as a context expansion mechanism that shifts the hallucination surface area to retrieval relevance rather than eliminating it.

Journey Context:
The belief is that giving the model the exact answer prevents it from making one up. In reality, RAG introduces 'motivated reasoning' where the model might still ignore the context if it strongly conflicts with pre-training, or it might hallucinate connections between disparate retrieved chunks. The 'lost-in-the-middle' effect means the model ignores retrieved context anyway, defaulting to parametric hallucinations.
