WHY IT NEEDS A POLICY

Why save_scene needs a policy

This tool creates or modifies data reversibly by persisting scene changes to disk storage. It falls under Write rather than Destructive because the operation is reversible (previous versions can typically be recovered via version control or backups, and the tool doesn't inherently delete data).
