[architecture] Agent runs out of context window or retrieves irrelevant history from vector DB

Implement tiered memory \(working memory in-context, archival memory in vector DB\) with explicit routing and summarization, moving data between tiers based on relevance and capacity.

Journey Context:
Agents either try to cram everything into the context window \(hitting limits, degrading attention\) or dump everything into a vector DB \(losing sequential coherence and suffering from multi-hop retrieval failure\). The MemGPT architecture solves this by treating the LLM as an OS: context window is RAM \(fast, limited\) and vector DB is disk \(large, slow\). The agent must explicitly manage paging/eviction between them rather than hoping retrieval will magically work.
