WHY IT NEEDS A POLICY

Why merge_videos_tool needs a policy

Merging videos creates new composite media files by combining and modifying existing video data. This is a Write operation because it produces new or modified data artifacts reversibly—the original videos remain intact and the merge can be undone by deleting the output. It does not execute arbitrary code (Execute), permanently destroy data (Destructive), or involve financial transactions (Financial).

From the tool's definition Tool name 'merge_videos_tool' and description '合并多个视频' (merge multiple videos) indicate creation/modification of video files through combining existing clips.
