[architecture] Old memories polluting current context window and causing hallucinations

Implement memory decay or scoring. Only inject memories with high recency/relevance scores into the prompt. Use a working memory buffer that is flushed or deprioritized when the task or session changes.

Journey Context:
Agents often dump all retrieved memories into the context. If a user changes topic, old memories cause confusion or the agent hallucinates connections between unrelated contexts. The tradeoff is potentially forgetting useful long-tail info vs. context pollution. Recency weighting and explicit working memory boundaries prevent stale data from overriding current instructions.
