[architecture] Single-step vector retrieval fails to answer multi-hop questions

Implement iterative retrieval where the agent retrieves a fact, reasons about it, and uses it to formulate a subsequent retrieval query to find the connecting fact.

Journey Context:
If a user asks a complex question, a single vector search won't find the answer because the answer spans two disconnected facts. Agents often fail because they try to retrieve the final answer directly. Multi-hop retrieval allows the agent to traverse the knowledge graph or vector space step-by-step, gathering intermediate evidence to synthesize the final answer.
