WHY IT NEEDS A POLICY

Why discord_remove_role needs a policy

Removing a role from a member modifies their permissions/access reversibly — the role can be re-added. This is a Write operation (reversible modification of member state). Severity is medium because misuse could strip important roles from members, disrupting access, but it is recoverable.
