[architecture] Storing all agent state in vector database instead of context window

Use the context window for the current active reasoning stack and immediate action plan. Use the vector store only for cross-session episodic memory and semantic knowledge. Treat the context window as L1 cache and the vector store as L2/L3.

Journey Context:
Developers often over-rely on RAG, forcing the agent to retrieve its own working state from a vector DB on every turn. This introduces retrieval latency, loss of exact word-for-word precision \(vectors approximate\), and omission risk if the retrieval query doesn't match the stored state. Working memory must stay in the context window to guarantee exact, zero-latency access to the current execution state. Vector DBs are for fuzzy, long-term recall, not operational state.
