Save the containerd-worker configuration before enabling BuildKit, then restart the service to load the new settings even if it is already running. Starting the daemon before editing its configuration leaves the old worker configuration active. Signed-off-by: xinjun.jiang <xinjun.jiang@daocloud.io>

This is not needed for OCI worker mode.

Write the rootful containerd-worker configuration before enabling BuildKit, then restart the service so an already running daemon uses the new worker settings. The previous sequence started the service before editing its configuration and left it running with the old settings.
Validated with a private BuildKit 0.34.0 daemon and empty task-owned containerd namespaces: replaying the old command order leaves the worker on its original namespace, while the corrected order switches it to the configured namespace. Service actions were mapped to the private daemon; host systemd and configuration were not changed. The daemon, socket, state directory and namespaces were removed afterward. Codespell,
