WHY IT NEEDS A POLICY

Why photoshop_flatten_image needs a policy

This tool modifies document structure by consolidating layers into a single background layer. While the change is technically reversible via undo in Photoshop, once the document is saved or the undo history is cleared, the layer information is lost. This is a Write operation because it permanently alters the image composition in a way that destroys layer data if not quickly undone.

From the tool's definition photoshop_flatten_image: 'Flatten all layers into a single background layer' - this operation merges and modifies the image structure by combining multiple layers into one, which changes the document state.
