[architecture] Vector similarity search fails on multi-hop reasoning queries

Implement an iterative retrieval loop where the agent searches, reads the results, generates a refined search query based on the new information, and searches again, or pre-process memories into a knowledge graph for traversal.

Journey Context:
Cosine similarity matches on surface semantics. If the bridge between two concepts isn't in the query, single-hop vector search fails. Knowledge graphs solve this but are rigid and hard to populate accurately. Iterative retrieval bridges the gap without requiring a perfect graph, though it increases latency and token usage.
