[architecture] Old memories polluting current context window

Implement a two-stage retrieval: semantic search followed by temporal recency weighting and a relevance classifier before injecting into the context.

Journey Context:
Agents often dump raw vector search results into the prompt. Over time, the vector store accumulates outdated states \(e.g., old file structures, deprecated APIs\). A pure vector search returns high-similarity but obsolete code. You need a decay factor or a re-ranker that filters out memories that contradict the current state, otherwise the agent will attempt to use deleted functions or old schemas.
