fix: compose network bug - try up/direct, fallback to stripped config

Docker Compose v2.20.1 fails to create containers when external
networks can't be connected. First try compose directly; if container
isn't created, strip networks from resolved config via JSON processing
and retry. Connect networks manually in both paths.
