Research direction

No source file, test, or entry point is identified in the report. Reproduce the #cpp failure with non-Insiders VS Code and version 1.22.5, then compare it with 1.22.4 and Insiders builds. Done means GitHub Copilot chat accepts #cpp without the reported undefined-property error in the affected version combination.
