* Added Arrayable support for SimpleDTO
* feat: Refactor SimpleDTO's isArrayable method
The code changes in `SimpleDTO.php` refactor the `isArrayable` method to improve readability and maintainability. The changes reorder the conditions to prioritize commonly used types and remove unnecessary checks. This ensures that the method accurately determines if a value is arrayable.
