Detailed Description

Thread-safe singleton pattern implementation with ownership management.

This file implements a robust singleton pattern with the following features:

• Lazy initialization with thread safety
• Exclusive ownership management using ownerPtr
• Controlled lifecycle management (init/clear/reset)
• Exception-safe operations
• Prevention of copy and move operations
• Runtime instance existence checking

The singleton ensures that only one instance of the templated type exists throughout the application lifetime, with proper initialization order and destruction guarantees.

Note

This implementation is not thread-safe for simultaneous init()/reset() calls. For thread-safe usage, ensure proper synchronization at the application level.

The singleton instance is automatically destroyed when the program exits or when explicitly cleared/reset.
