Why trim_video_tool needs a policy

This is a reversible write operation (the original file may still exist), not inherently destructive unless it overwrites the source. Given the context of a video editing pipeline, this is best classified as Write with medium severity, as misuse could result in unintended loss of video content if it overwrites the original.
