[architecture] Agent accumulates stale or contradictory facts across sessions, polluting new answers

Implement time-decay scoring and memory consolidation. Periodically summarize episodic memories into semantic knowledge, and delete low-confidence or outdated episodic nodes.

Journey Context:
Storing every interaction as a vector creates a write-heavy, read-lazy system. Over time, the embedding space gets noisy with outdated facts \(e.g., 'user lives in X' when they moved to Y\). Human memory consolidates: short-term episodic memory decays unless reinforced, then gets abstracted into long-term semantic memory. Agents need a cron job or post-step to merge/update semantic nodes and prune episodic ones.
