[architecture] Single-hop semantic search failing to find connected facts

Implement graph-based memory \(Knowledge Graph\) alongside vector storage, or use iterative retrieval \(query the DB, extract entities, query again\) to traverse relationships.

Journey Context:
Vector DBs excel at topical similarity but fail at relational traversal \(e.g., 'Who is the manager of the person who wrote the document I saved yesterday?'\). Agents get stuck because the intermediate step isn't semantically similar to the final answer. Tradeoff: Graphs require strict schema/entity extraction overhead; iterative retrieval adds LLM calls and latency.
