[architecture] Single-step vector search failing to connect related concepts across memory

Implement multi-hop retrieval: use the initial query to fetch a memory, then use entities/facts from that memory to formulate a secondary query to fetch the next piece, iterating until the context is complete.

Journey Context:
If a user asks 'What IDE does the lead dev of Project X use?', a single vector search will fail if the memory store has 'Alice is lead dev of Project X' and 'Alice uses Neovim' as separate chunks. Single-hop retrieval assumes all relevant information is co-located in the same text chunk. Multi-hop \(or graph-based traversal\) is required when knowledge is distributed across multiple atomic facts.
