[architecture] Agent accumulates stale facts that contradict current reality

Implement exponential time-decay weighting on memory retrieval scores and a background curation process that flags low-access, high-age memories for re-verification or deletion.

Journey Context:
'Memory grows forever' is a common anti-pattern. A user's address, API preferences, or project state changes over time. If memories don't decay, the agent might suggest a deprecated library it remembers from a year ago. Exponential decay ensures recent facts win ties. Re-verification prompts the user \('Are you still working on project X?'\) to explicitly prune dead state, preventing the agent from acting on ghost knowledge.
