socket_processor: Enforce inline rules
This change moves the global `processor` pointer into the
`SocketProcessor` class as a private static inline member.
This refactoring improves code quality by:
- Eliminating a global variable, which reduces namespace pollution.
- Enhancing encapsulation by managing the singleton instance within
its own class.
- Making the code cleaner and more maintainable.
