[architecture] Accumulating infinite memories causing retrieval latency and stale context

Implement an exponential decay score based on access frequency and time since last access; prune or archive low-scoring memories.

Journey Context:
Without decay, vector stores grow linearly, slowing retrieval and increasing storage costs. More importantly, old, irrelevant facts resurface and pollute the context. Ebbinghaus forgetting curve applied to agents means rarely accessed, old data should be archived or deleted, keeping the active working set small and highly relevant. The tradeoff is losing historical data, which can be mitigated by archiving rather than deleting.
