[architecture] Agent episodic memory fills up with redundant conversational turns making retrieval noisy

Implement a background consolidation process that clusters similar episodic memories and summarizes them into a single semantic memory, then deletes the original episodes.

Journey Context:
Storing every conversational turn as a vector is cheap but retrieval gets noisy \(the needle in a haystack of needles problem\). Storing only summaries loses granular details. The tradeoff is granularity vs. noise. The right call is a two-tier system: short-term episodic memory \(raw turns\) that gets asynchronously rolled up into semantic memory \(generalized facts\).
