Modern C++ refactoring intelligence. Scans and modernizes legacy C/C++98/11 code to C++17/20 standards. Detects: raw pointers, manual memory, C-style arrays, old containers, manual loops. Replaces with: smart pointers, RAII, std::array/vector, ranges, std::format, structured bindings, auto, constexpr, concepts, std::optional, std::variant. Actions: scan, analyze, refactor, modernize, upgrade, review, check C++ code. Patterns: memory leaks, null checks, iterator loops, string formatting, error handling, ownership semantics.
