[architecture] Old memories polluting current context window and derailing the agent

Implement a two-stage retrieval: fetch broadly via vector similarity, then rerank/filter strictly by temporal relevance and current task intent before injecting into the prompt.

Journey Context:
Agents often dump all retrieved vector matches into the context. This eats up token space and derails the LLM with outdated state \(e.g., a file that was deleted 3 sessions ago\). Vector similarity alone does not respect time. Reranking or filtering by recency/decay after retrieval prevents stale context from overriding fresh facts, ensuring the agent acts on the current state of the world.
