[architecture] Agent memory grows infinitely causing retrieval degradation

Implement an exponential decay score for memories based on access frequency and time since creation, combined with a periodic memory consolidation step that summarizes/forgets low-score items.

Journey Context:
Storing every interaction in a vector DB seems safe but leads to 'memory bloat' where retrieval latency increases and precision drops. Alternatives like TTL on memories lose frequently used facts. Exponential decay with access-time boosting \(like LRU cache logic applied to vectors\) preserves important facts while letting transient ones fade, maintaining a high-signal memory pool.
