feat: Add freestanding C++17 OOP kernel subsystem and interactive Snake Game

- Add freestanding C++17 runtime with operator new/delete, pure virtual handlers, and global constructor execution in kernel/cpp/cxx_runtime.cpp
- Implement C++ Object-Oriented telemetry and hardware services with polymorphism in kernel/cpp/cpp_module.cpp and include/kernel/cpp_kernel.h
- Add interactive ANSI Snake Game in userland/lazybox/snake.c with real-time keyboard control and automated simulation mode
- Initialize C++ subsystem during kernel boot step [8/14] in kernel/main.c
- Add LazyBox applets: 'snake', 'cppinfo', and 'cpptest'
