[architecture] Retrieved memories are polluting the context window and confusing the LLM

Implement a two-stage retrieval pipeline: vector search for candidate recall, followed by a cross-encoder or LLM-based relevance filter that scores candidates against the current query before injection into the context window.

Journey Context:
Naive RAG dumps top-K vectors straight into context. If K is too high, or embeddings are stale, the LLM suffers from 'lost in the middle' or hallucinates by combining contradictory contexts. A re-ranker or filter ensures only highly contextual memories consume the precious context window, trading a little latency for massive precision and preventing old context from derailing new answers.
