Unity CLI

One CLI (cs) drives the Unity Editor/Player. The default authoring surface is grouped into six agent-facing domains so only the relevant schema enters context; control-plane and project custom commands use explicit views. cs list-commands is a control-plane CLI discovery operation, not the canonical package contract command/list. Its CLI flags are never command/list arguments, and discovery invocations must not be represented as canonical command routes. Only use command/list when the user explicitly requests that package contract. The records returned by discovery carry authoring, custom, or control-plane tiers.
