WHY IT NEEDS A POLICY

Why save_current_layout needs a policy

This tool creates new persistent layout data without deleting or overwriting existing layouts. While it modifies the application's stored layouts, the action is reversible (the saved layout can be deleted or overwritten later). It does not execute arbitrary code, move money, or permanently destroy data.

From the tool's definition Tool description states 'Save the current window arrangement as a new Moom layout' — this creates and stores a new layout configuration, a reversible write operation.
