[architecture] Raw episodic memory streams grow linearly, eventually slowing down retrieval and overwhelming the agent with trivial details

Implement an asynchronous reflection phase where the agent periodically synthesizes lower-level episodic memories into higher-level semantic insights, then archives or deletes the raw episodic memories.

Journey Context:
Storing every single action or utterance as a memory \(the 'log everything' approach\) seems safe but scales terribly. The vector store gets polluted with noise \('User typed hi', 'Agent responded Hello'\). The Generative Agents architecture solved this with a reflection mechanism: when the episodic memory store reaches a threshold, the agent queries its own memory to generate a higher-level summary \(e.g., 'User frequently asks about Python, likely a developer'\), saves that as a new semantic memory, and prunes the raw logs. This keeps the memory store dense with signal and small in size.
