[architecture] Using a vector database as the sole working memory for an agent

Implement a tiered memory architecture: use the LLM context window as volatile working memory, and vector databases or knowledge graphs as long-term storage, moving data between them explicitly via context management operations.

Journey Context:
Agents often fail at multi-step tasks because they push intermediate steps to a vector DB and lose the sequential thread. Vector search is semantic, not sequential. Working memory \(context\) holds the current plan and state; long-term memory holds historical facts. Blurring them causes state loss and hallucination, as the agent forgets what it just did in favor of semantically similar but temporally wrong past events.
