v1.60.1

Changed

• Internal groundwork: the container CLI is starting to move behind a small ContainerBackend seam instead of docker … calls scattered inline. This release routes the read-only commands in the monitor and the Web UI (ps, inspect, image inspect, logs, stats) through it; the update engine is untouched. No behaviour change — the commands sent are byte-identical — it's the groundwork that makes a real podman backend, and eventually remote hosts, a contained change rather than edits in ninety places.
