[architecture] Vector store growing infinitely and degrading search quality

Implement an importance-weighted exponential decay mechanism. Periodically compute a forgetting score and evict or archive memories below a threshold, unless explicitly pinned.

Journey Context:
Vector stores degrade as they scale \(search returns irrelevant results\). People just add data forever. The tradeoff is losing potentially useful long-tail info vs. maintaining high retrieval precision. Exponential decay mimics human memory; importance weighting preserves core facts while allowing trivial details to fade.
