[research] Multi-hop reasoning error cascades and intermediate hallucinations

Decompose multi-hop queries into single-hop sub-queries, execute them sequentially, and ground each intermediate step's output before proceeding to the next.

Journey Context:
End-to-end generation for multi-hop questions often fails because the model guesses the intermediate entity without verification. If the intermediate step is wrong, the final step is guaranteed to be wrong. Iterative retrieval and grounding \(like IRCoT\) breaks this cascade by forcing factual verification at each step.
