WHY IT NEEDS A POLICY

Why sheets_duplicate_sheet needs a policy

Duplicating a sheet creates a new copy of an existing sheet — this is a reversible write/create operation. The duplicate can be deleted if unwanted, so it is not destructive. No code execution or financial impact is involved. Severity is medium because it could bloat a spreadsheet or expose data in unintended locations if misused.
