WHY IT NEEDS A POLICY

Why create_map_event_draft needs a policy

This tool creates or stages new map event data within an RPG Maker MV project. It modifies project state by adding content, but the 'draft' pattern means changes are not yet committed to disk—they can be discarded or reviewed before application. This is Write (reversible creation/modification), not Destructive.

From the tool's definition Tool name 'create_map_event_draft' and description 'Draft a map event' indicate content creation. The 'draft' suffix and server description stating 'safely write content' suggest changes are staged but reversible via discard_pending_changes.
