WHY IT NEEDS A POLICY

Why set_navigation_layers needs a policy

This tool modifies a node's navigation layer configuration (bitmask), which is a reversible change to game object properties. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or cause financial impact.

From the tool's definition Tool name 'set_navigation_layers' and description 'Set the navigation layer bitmask on a navigation node' indicate modification of node properties. The term 'set' combined with 'bitmask' modification confirms write operation without deletion.
