WHY IT NEEDS A POLICY

Why tilemap_fill_rect needs a policy

This tool creates or modifies game data (tilemap tiles) reversibly. It does not delete data permanently—filled tiles can be changed again by subsequent operations. It is not Destructive because the operation is undoable (tiles can be refilled with different values). It is not Execute because it doesn't run arbitrary code or trigger external side effects; it performs a scoped, well-defined modification.

From the tool's definition Tool name 'tilemap_fill_rect' and description 'Fill a rectangular area of a TileMap with a specific tile' indicate modification of game level data. The verb 'fill' modifies existing tilemap state by overwriting tile values in a rectangular region.
