Text/Box/Static/Transform read children via slots but never surfaced
`children` on their JSX `$props`. Under the automatic JSX runtime
(jsx: react-jsx + jsxImportSource: vue), children are passed as a
`children` prop, so `<Text>x</Text>` failed to type-check. Add a
type-only WithChildren cast that declares optional `children` on $props;
Vue routes that prop to the default slot at runtime, so there is no
runtime change.
