WHY IT NEEDS A POLICY

Why set_auto_accept needs a policy

This tool modifies a configuration or policy setting (auto-accept behavior for staged script diffs), which is a reversible write operation. It doesn't execute code, delete data, or move money. Severity is medium because misconfiguring auto-accept could cause unintended script changes to be automatically applied in Roblox Studio, but the effect is reversible.
