Pull request overview
This PR fixes TypeScript type inference for the onCaughtError option in RenderOptions to properly support React 19. The fix addresses an issue where the conditional type check was too strict, requiring the property to be non-optional when React 19's RootOptions defines it as optional.
Key changes:
- Updated the conditional type in
RenderOptionsto check for optionalonCaughtError?instead of requiredonCaughtError - Changed test file directive from
@ts-expect-errorto@ts-ignoreto maintain compatibility with both React 18 and 19 type checking in CI

| File | Description |
|---|---|
| types/index.d.ts | Made onCaughtError property optional in the conditional type check to match React 19's optional property definition |
| types/test.tsx | Updated test comments and TypeScript directive to use @ts-ignore for cross-version compatibility during CI testing |
