Add a new playground demonstrating React 19 SSR error handling patterns: - onError callback on renderToReadableStream for server-side error logging - digest property for opaque error identification across server/client - captureOwnerStack for owner-chain debugging in development - SSR-to-CSR fallback when the server shell fails to render - onRecoverableError on hydrateRoot for hydration mismatch logging - ErrorBoundary component catching both SSR and client-only errors Includes two error scenario pages (ThrowsRender, ThrowsEffect), integration tests, and a README documenting each pattern.
