The unexpected (compiler) warnings in Clang-Tidy make me wonder if this is a mislabeled Clang 23 instead (it seems the version bumped was botched as well - see llvm/llvm-project#182959) ...

No, these warnings were all introduced before LLVM 22. The problem is that packages are being outdated (tracked in llvm/llvm-project#164705).

I think a better workaround would be to revert to LLVM 21 if that works. I will give it a spin in simplecpp.

That did the trick for simplecpp: danmar/simplecpp#630. So please revert the version to LLVM 21 for now.
