// Object Wrapper
/**
* @brief Utility wrapper that bridges factory registration and shared ownership.
*
* ObjectWrapper provides a high-level interface to handle objects that can be
* both registered in the ObjectFactory and managed through shared ownership
* using SmartPointer.
*
* One of its key roles is static registration: when instantiated with a
* class name string, it automatically registers a factory function for type T
* in the ObjectFactory singleton. This allows the factory to subsequently
* create instances of T dynamically by name.
*
* It supports multiple initialization paths, including factory-based
* construction and direct model wrapping.
