Keep selected props required in React output target (e.g., modal open)

[apenab]

Hi! When generating React proxies with @stencil/react-output-target, all props become optional. For modals/dialogs we need open to be required in React.

@Component({ tag: 'nova-modal' })
export class NovaModal {
  /** Controls visibility; should be required */
  @Prop({ reflect: true }) open!: boolean;
}

Problem: In React, open is emitted as optional, allowing without open.
Why it matters: Design-system components often have contractual props; compile-time enforcement prevents misuse.

Ask: Is there a built-in way to keep certain props required in the generated React types? If not, would you consider:
• Config: requiredProps: { 'nova-modal': ['open'] }
• Hint: @prop({ required: true }) or JSDoc @required propagated to React d.ts
• Hook: a callback to post-process emitted prop types
