 Frontend ticket for the custom CLI slash-command UX. When the user types `/` at the start of the composer, show a contextual menu with a small set of matching command suggestions and short descriptions; refine suggestions as the user types (`/c` => commands starting with `c`). Support keyboard navigation and selection. This ticket is only about the custom CLI UX and consumption of the unified command contract; it must not hardcode a closed list of commands in the UI.
