[architecture] Agent memory growing indefinitely causing retrieval degradation

Implement exponential time-decay weighting on memory access scores, combined with periodic consolidation of older memories into higher-level abstractions.

Journey Context:
Storing every interaction creates a noisy vector space where recent, important facts are drowned out by trivial, old ones. Just relying on recency isn't enough; importance must also be tracked. The Generative Agents paper defines a memory score as recency \* importance \* relevance. Consolidating old memories \(e.g., summarizing 5 interactions into 1 summary\) reduces vector DB clutter while preserving knowledge, trading granular access for storage efficiency and retrieval accuracy.
