Local devpush VM:
  pnpm vm:setup          Create/start the VM with Docker and a reachable local IP.
  pnpm vm:install URL    Enroll this VM using a generated installer, pinning its IP.
  pnpm vm:test           Set up the VM and run real Compose/Traefik tests directly.
  pnpm vm:stop           Stop the VM, keeping its disk.
  pnpm vm:destroy       Delete the dedicated test VM and all its data.
Requires macOS and Lima; tests also require Go on the host. VM name: devpush-test.
