[architecture] Agent memory growing indefinitely until retrieval latency spikes and relevance drops

Implement memory decay by attaching a recency weight to memory retrieval scores, and periodically run a curation step to consolidate or delete low-access, low-relevance memories.

Journey Context:
Human memory naturally decays; agent memory usually doesn't unless forced. Without decay, the vector space becomes dense, increasing false positives in similarity search. Alternatives like LRU cache work for exact matches but fail for semantic overlaps. Best call: explicit time-weighted decay combined with episodic consolidation to maintain signal-to-noise ratio.
