Freeze the 1.0 CLI Cluster command tree #988

Parent

Spec: 1.0 tree cleanup and release contracts

What to build

Expose only the agreed Cluster operations over SSH contexts and remove the retired workflows, duplicate Service commands, aliases, and Go-template version output.

Acceptance criteria

• CLI shape tests assert cloud, machine, service, volume, ingress, ctx, project, proxy, ps, and version.
• The removed command groups, duplicates, aliases, and version -o are absent from parse and help; remaining handlers work.

Blocked by

• Remove Compose authoring from Core
