[architecture] Agent accumulates infinite facts in long-term memory causing retrieval degradation

Apply a time-decay or access-decay scoring mechanism to memories. Periodically run a curation step to consolidate or delete low-score memories.

Journey Context:
Vector DBs just grow indefinitely. As they grow, top-K retrieval gets noisier \(the 'needle in a haystack' problem gets worse\). Agents need a forgetting mechanism like human memory. Without it, retrieval precision drops over time, and embedding costs rise.
