Role-local library/ and module_utils/ resolve only inside the owning
role's task scope, so kcadm update tasks invoked from other contexts
in the swarm flow could not find keycloak_kcadm_update. ansible.cfg
already declares ./library and ./utils as the global paths; the filter
plugin and unit tests follow the move. Helper narrows its parse guard
to ValueError.
