[research] Fabricating bridging entities in multi-hop questions

Decompose multi-hop queries into explicit, sequential single-hop tool calls. Do not ask the LLM to answer the multi-hop question in one pass. Call tool 1 to find the intermediate entity, extract the exact value, then call tool 2 using that specific value.

Journey Context:
LLMs struggle with compositionality. When forced to answer a multi-hop question in one shot, they often hallucinate the intermediate entity because the forward pass cannot reliably bridge the gap. By forcing tool-use decomposition, the intermediate entity is grounded by an external system, breaking the hallucination cascade.
