[architecture] Single-step vector retrieval failing to answer complex multi-part questions

Implement iterative retrieval where the agent retrieves a chunk, evaluates it, and uses it to formulate a secondary query to retrieve the next piece, rather than trying to fetch everything in one pass.

Journey Context:
A single vector search assumes the query contains all the semantics needed to find the answer. For 'Compare the architecture of project A with project B', a single query won't match both. Multi-hop allows the agent to traverse the knowledge graph or vector space iteratively, building context step-by-step just like a human researcher.
