[counterintuitive] RAG fixes hallucination

Implement strict citation verification and retrieval evaluation. RAG shifts the problem from 'hallucination of general knowledge' to 'hallucination of retrieved context' or 'context ignorance'.

Journey Context:
Developers assume providing context forces the model to use it. In reality, if the retrieved context conflicts with strong pre-trained priors, or if the context is irrelevant/noisy, the model will often ignore the context and hallucinate anyway, or hallucinate connections between disjoint retrieved chunks. RAG without strict grounding constraints just gives the model a new source to hallucinate about.
