C++20 modules support

Hello CodeQL team,

I see that the documentation currently states that “C++20 modules are not supported.”
I’d like to ask if there is any ongoing work or roadmap item planned to add support for C++20 modules in the C/C++ extractor and CodeQL libraries.

Modules are becoming increasingly common in large C++ codebases, and understanding whether this feature is planned (and roughly when) would help us plan future analysis integration.

Thanks a lot for any insights you can share!

The issue names no source files, tests, or entry points. Start by reviewing the documentation statement that C++20 modules are unsupported and the current C/C++ extractor and CodeQL library support. Done would require a decided support plan or implementation scope, not a single localized change.
