[counterintuitive] use RAG to stop LLM hallucinations

Implement explicit 'insufficient context' handling and retrieval evaluation in RAG pipelines, as RAG does not eliminate hallucination but shifts it from fabricating parametric knowledge to misinterpreting or conflating retrieved context.

Journey Context:
The consensus is that giving the model the 'right answer' in the context prevents it from making things up. In reality, if the retrieved context is partially relevant but insufficient, or contains conflicting information, the model will confidently hallucinate by blending the context with its internal weights. Furthermore, models are poorly calibrated to say 'the context doesn't say'. RAG changes the failure mode to 'context-confabulation', which is harder to detect than pure parametric hallucination.
