[architecture] Never deleting or decaying memories, leading to an ever-growing index where obscure historical facts drown out recent context

Implement a time-decay weighting on memory retrieval scores. Combine semantic similarity with a recency function \(e.g., exponential decay\) so that older, rarely accessed memories are naturally suppressed unless explicitly requested.

Journey Context:
Human memory degrades for a reason: infinite retention leads to retrieval interference. In vector databases, an old fact with high cosine similarity will outrank a recent, slightly less similar fact. By applying a recency bias, you ensure the agent prioritizes the current state of the world over historical noise, mimicking the Ebbinghaus forgetting curve.
