Deploy GitLab from the official CNG CE images as six services: webservice (puma) and sidekiq scale to the topology default, workhorse is the sole HTTP entry, gitaly and a one-shot migrations job are pinned singletons, shell runs gitlab-sshd. The Omnibus container, its Dockerfile and the GITLAB_OMNIBUS_* config groups are removed. All rails/workhorse/shell/gitaly configs and shared secrets are pre-rendered by Ansible and mounted read-only; eleven credentials land in meta/schema.yml including an rsa_pem_2048 OIDC signing key (new value_generator algorithm). Postgres, redis and S3 object storage ride the existing lookups; OIDC, SMTP, the public SSH port and the root password are preserved. compose_volumes gains a per-volume nfs:false opt-out so the gitaly repositories volume stays node-local in swarm (upstream forbids git repositories on NFS); nfs_prep skips volumes without driver_opts accordingly. The Nextcloud gitlab integration execs the CNG rails runner. ruby_single_line dies with its only consumer; ruby_dq keeps test coverage. Ports (8181/8080/2222/8075/3808/9122) and service names resolve from single SPOT declarations in meta/services.yml via vars constants; the version pin sits on the webservice image pair so the updater can bump it. Live-validated in compose up to all six services healthy and migrations completed; fresh-install-only semantics for existing Omnibus data are documented.

A swarm docker stack deploy env-file value must be a single physical line; the
multi-line GITLAB_OMNIBUS_CONFIG was read as separate whitespace-named env
entries and aborted the deploy. Add a depth-aware ruby_single_line filter that
collapses the Ruby program to one line (statement-boundary newlines at bracket
depth 0 become ';', newlines inside an open bracket or a string become a space
so hash/array literals like the OIDC omniauth_providers stay valid) and apply it
on the swarm branch only; compose keeps the multi-line value unchanged.
Covered by tests/unit/plugins/filter/test_ruby.py (10 cases incl. a realistic
omnibus config, escaped quotes and nested literals).
