[architecture] Vector search failing for multi-hop reasoning questions

Replace single-shot vector retrieval with iterative retrieval \(ReAct-style memory querying\) or a graph-based memory architecture \(Knowledge Graph\) to traverse relationships between entities.

Journey Context:
If an agent needs to answer 'Which library did the user prefer for the project we started last Tuesday?', a single vector search will likely fail. It might find 'last Tuesday' or 'library preferences' but not the intersection. Single-shot RAG is fundamentally limited to single-hop proximity. Iterative retrieval allows the agent to find 'last Tuesday's project', extract the name, and search again for that project's library preferences.
