WHY IT NEEDS A POLICY

Why paint_tiles needs a policy

This tool creates or modifies game scene data (tilemap tiles) reversibly. A user or agent could repaint over changes, and the operation doesn't irreversibly delete data or execute arbitrary code. It fits Write category. Severity is medium because misuse could corrupt level design, but effects are reversible and localized to a tilemap layer.

From the tool's definition Tool name and description: 'paint_tiles' / 'Paint multiple tiles in a TileMapLayer in a single batch operation' — directly modifies tilemap data by painting/changing tiles.
