WHY IT NEEDS A POLICY

Why create_navigation_region needs a policy

This tool creates new game objects (navigation region nodes) in the Godot scene, which is a reversible Write operation. It modifies the project state by adding nodes but does not delete, execute arbitrary code, or trigger financial operations. The severity is medium because misuse could disrupt game navigation systems, but the impact is limited to scene structure and is easily undone.

From the tool's definition Tool creates a NavigationRegion2D or NavigationRegion3D node, which is a data structure modification in the Godot scene graph. The description uses 'Create' and the tool adds a new node to the game project.
