Summary
This PR fixes a flickering issue when using react-select with server-side rendering (Next.js, TanStack Start).
The root cause was that prerendering was not working correctly in these environments, causing the selected value to appear only after the JavaScript loaded, which led to CLS issues.

Solution
To support SSR, prerendering was added to the Select components, mainly for the Select Options. Components that previously did not support SSR were replaced with div elements so that prerendering would work correctly. With prerendering in place, we now iterate through the Select component’s children tree to find the selected item and use it as the value for the correct prerendered output.
