[counterintuitive] RAG fixes hallucination

Implement hybrid search, reranking, and strict context filtering; explicitly instruct the model to state 'I don't know' if the context is insufficient.

Journey Context:
Developers assume providing external documents forces the model to use them, eliminating made-up answers. In reality, noisy or conflicting retrieved chunks cause 'context-confounded hallucinations' where the model blends retrieved text with its internal parametric memory, or confidently hallucinates connections between disparate chunks. RAG shifts the failure mode from pure invention to misattribution and context-ignoring.
