[architecture] Cross-session memory grows infinitely, degrading retrieval accuracy and increasing latency

Implement episodic memory consolidation: periodically compress raw conversation logs into summarized semantic memories, and delete or archive the raw episodic traces after a configurable TTL.

Journey Context:
Storing raw chat transcripts per session makes cross-session persistence easy initially, but over time, the sheer volume of near-duplicate or trivial vectors creates a 'needle in a haystack' problem for the retriever. Human memory consolidates episodic memories into semantic ones. An agent architecture must mimic this: extract facts/preferences from a session, store them as semantic nodes, and then discard the raw session transcript \(or move it to cold storage\) to keep the active retrieval index dense and high-signal.
