Prove gitlab — the exemplar tools-only, outbound-only external-SaaS
integration — installs: a scenario assigning gitlab to one node, and a test
asserting the mesh-runtime-gitlab container comes up and stays up, logs
[mesh-tools] serving 23 tool(s), binds its serve queues on the broker, and
gets its own scoped account — all with NO valid GitLab token, the case the
Servarr lesson is about.
No gitlab arm is needed in build-module-runtime.sh: gitlab speaks HTTP and
needs no extra CLI in the image.
