/**
 * ⚙️ C & C++20 LANGUAGE RUNNER ADAPTER ⚙️
 * =======================================
 * Implementiert das LanguageRunnerAdapter-Interface für C & C++20:
 * - Syntax-Highlighting & Monaco C/C++ Modus
 * - Simulation von printf, std::cout, Pointer, RAII & Smart Pointern
 * - GoogleTest (gtest) Testsuite-Runner für TEST() Assertions
 * - 100% Client-Side Sandbox ohne Serverkosten
