Report #22799

[architecture] Single vector search failing to connect related concepts across time

Implement multi-hop retrieval where entities or timestamps from the initial retrieval are used as queries for subsequent retrievals.

Journey Context:
A user asks 'Where is the file I worked on right after I fixed the auth bug?'. A single vector search for 'auth bug file' won't find the subsequent work. You need to retrieve the 'auth bug' memory, extract the timestamp, and query for memories immediately following it. Tradeoff: Multi-hop is slower and can drift off-topic if not constrained, but necessary for temporal/relational queries.
