/**
* ui-command browser half on a real cordis Context with fake slash/slots
* faces and real session scopes: the plugin body mounts CommandService as
* `command`, the popupSelect shell registers into conversation.input.overlay
* through slot declaration injection with a per-session inject (sessionId →
* scope → popupFor; unknown id fails loud), both fold up on fiber disposal
* (HMR safety), and the service satisfies the frozen CommandServiceContract.
