[counterintuitive] RAG fixes hallucination

Implement robust context ranking, deduplication, and source attribution validation; treat RAG as a context-shaping tool, not a hallucination cure.

Journey Context:
The belief is that giving the model the 'right answer' in the prompt prevents it from making things up. Counterintuitively, RAG can introduce new hallucination vectors: conflicting documents cause the model to synthesize a false compromise, noisy context causes attention dilution, and the model often hallucinates that the retrieved text says something it doesn't \(misattribution\). The 'Lost in the Middle' phenomenon proves models ignore relevant context if it's buried in noise, leading to the exact hallucinations RAG was meant to solve.
