WHY IT NEEDS A POLICY

Why layer_rename needs a policy

This tool modifies layer metadata within the SVG canvas application in a reversible manner. It creates or updates data (the layer name) without destructive, financial, or executable side effects. The scope is limited to renaming within the application's internal state. This is typical Write-category functionality.

From the tool's definition Tool name 'layer_rename' and description indicate renaming a layer (메타데이터 수정 = metadata modification). The description in Korean translates to 'Renames a layer', which modifies layer properties reversibly without deleting data or executing external operations.
