[frontier] Naive RAG retrieves irrelevant context and fills the token window with noise while missing critical working memory, causing agents to lose track of goals

Implement a two-tier memory hierarchy: 'Working Memory' \(context window\) for active task state, and 'Reference Memory' \(archival store\) with explicit page\_in/page\_out functions triggered by the LLM itself

Journey Context:
Teams start with simple vector search RAG, then hit context window limits or retrieval noise. The MemGPT paper \(2023\) introduced the OS analogy: the LLM is the CPU, context window is RAM, and vector store is disk. The key insight is giving the LLM explicit memory management tools \(page\_in, page\_out, search\). This replaces implicit 'stuff all docs into context' with explicit memory pressure handling. Production systems in 2025 use this to handle hour-long sessions without losing task context, something naive RAG cannot do.
