svc-runner started its stack with 'compose --chdir /opt/github-runner up'
and no --project, so the wrapper named the project after the directory,
github-runner, while every other role uses its entity name. Pass 2 of the
swarm drill in fork run 41744154601 (svc-runner#0) then stopped in the
pre-flight: network 'runner' belongs to compose project 'github-runner'.
The deploy now passes --project from entity_name, and a unit test renders
the real task, runs the real wrapper and checks the pre-flight accepts the
network it creates.
