compute_external_network_roles() + compose_external_networks lookup expose which foreign provider networks a compose project references as external, so the swarm deploy path can pre-create them. network/create.yml probes for an existing network instead of unconditional state:present (the module's delete+recreate on attached networks crashed redeploys) and hard-fails on driver drift instead of silently skipping it.

Mocks the Ansible-side machinery and asserts the plugin glue resolves

variables and chains ``compute_external_network_roles`` correctly. The
