[architecture] Agent fails to answer questions requiring connecting multiple distinct memories

Implement iterative retrieval \(multi-hop\) where the LLM can issue multiple sequential search queries based on the results of previous queries, rather than trying to fetch all necessary context in a single top-K vector search.

Journey Context:
Standard RAG assumes the answer is contained within a single contiguous text chunk. In complex agent tasks \(e.g., 'Who was the project manager for the API redesign that caused the outage?'\), the required facts are scattered. A single vector query will likely return chunks about 'API redesign' or 'outage', but miss the link. The tradeoff is latency \(multiple retrieval steps\) vs. accuracy. For deep reasoning tasks, the latency of multi-hop retrieval is a necessary cost.
