WHY IT NEEDS A POLICY

Why leaveAllRoles needs a policy

This tool modifies role membership by removing a user from all roles in an application. While it changes data, role assignments can typically be reassigned, making it Write rather than Destructive. However, the blast radius is high because removing all roles from a member could effectively revoke all their access/permissions across an entire application.

From the tool's definition 将指定成员退出应用下所有角色 — removes a member from all roles under an application
