WHY IT NEEDS A POLICY

Why neptime_add_watch_later needs a policy

This tool creates or modifies data reversibly by adding a video to a user's watch-later list. It is a Write operation because: (1) it persists new state (the video added to the list), (2) the action is reversible (the video can presumably be removed), and (3) it has no destructive or execute characteristics.

From the tool's definition Tool description states "Add a video to your watch later list" which creates/modifies user data (a watch-later collection). The Args show it takes a video_id and Returns a Confirmation, indicating successful data modification.
