Container-plane docker now routes through the mode-aware helpers instead of sudo: simple calls (exec/ps/run/build/images/inspect/port/logs across ~15 app/check scripts) -> runFileOp docker (rootless socket as the install user; rooted via the docker group). The cd && docker compose paths drop the sudo on the rooted branch (the rootless branch already used dockerCommandRunInstallUser -- byte-identical now, manager-ready later); gluetun, which had no rootless branch, now uses dockerCommandRun so force-recreate works in both modes.
