Research direction

Reproduce the report with the supplied c_cpp_properties.json, compilerPath, VS 2022 toolchain, and main.cpp, then compare the extension's displayed _MSC_VER with the compiler's expected value. Use the C/C++ diagnostics log to trace compiler-default detection; done means the VS 2022 configuration reports 1944 rather than 1951.
