<TUI> is the terminal counterpart to <UI>: it declares
the React entry an OpenTUI-capable client should render for terminal
monitoring. It renders nothing in the workflow graph; clients read the
declaration from workflow metadata and pick the terminal host.
Props
<TUI> accepts the same view fields as <UI>: entry, source,
exportName, title, props, and literal children. Prefer entry for a
real terminal app, so the OpenTUI host loads the full React component tree.
