[counterintuitive] RAG fixes hallucination

Implement RAG alongside strict context adherence prompting \(e.g., 'Answer only using the provided context'\) and retrieval evaluation, as models can still hallucinate by blending parametric memory with context or ignoring irrelevant context.

Journey Context:
The consensus is that providing external documents via RAG stops models from making things up. In reality, RAG shifts the failure mode rather than eliminating it. Models often suffer from 'confabulation' where they merge retrieved facts with their outdated parametric knowledge, or they hallucinate that the retrieved context contains the answer when it doesn't. If the retrieval step fetches irrelevant chunks, the model might just hallucinate anyway, using the irrelevant context as a springboard.
