Support React 19

[honia19]

The current library doesn't support React 19. Do you have plans to support React 19 and milestones please. Thank you.

React on Rails Pro supports advanced features, like React Server Components. It's in beta now.

Please let me know if you'd like to book a demo or email me if you would like to learn more!

React on Rails itself does support React 19, you can see the demo app now uses it: #1677.

If you have more specific issues, please file them.
