fix: Implement proper virtual destructor and RAII pattern in Valuable…

… class

- Add noexcept virtual destructor with default implementation
- Preserve shared_ptr based RAII pattern
- Maintain virtual Clone() and Move() for proper copying
- Keep memory management methods like IsSubObject and SharedFromThis

This implements proper memory management while avoiding extensive interface changes.
