[architecture] Using single vector similarity search to retrieve memories for complex, multi-hop questions

Implement multi-hop retrieval \(e.g., Graph RAG or iterative retrieval\) where finding one memory allows the agent to query for related memories connected by entities or temporal sequences.

Journey Context:
Vector search is great for semantic similarity but fails at relational queries. If the agent needs to answer 'What library did I use for the project I started last week?', a single search will not work. It needs to first retrieve 'Project X started last week' and then retrieve 'Library Y used for Project X'. Representing memories as a graph \(entities and relations\) or using an LLM to iteratively refine search queries based on intermediate results bridges this gap.
