WHY IT NEEDS A POLICY

Why backup_memories needs a policy

This tool writes memory data to a backup file. It is a data export/write operation — it creates a new file containing memories. It does not delete or modify existing data, so it is not Destructive. Since it creates/writes a backup artifact, Write is the most appropriate category. Misuse could expose sensitive conversation memories, hence medium severity.

From the tool's definition 備份到文件 (backup to file), 導出短期和長期記憶 (export short-term and long-term memories), 包含完整的元數據和時間戳 (including complete metadata and timestamps)
