I can explain this part: as described in [this comment](https://github.com/llvm/llvm-project/issues/185108#issuecomment-4021021907), clang-tidy's infrastructure does some post-processing of the checker results in `DiagnosticRenderer` which hides the deficiency in the checker; clangd does not do such post-processing.

The test looks good to me, but I'll leave it up to @vbvictor to say whether the fix approach in the checker implementation is the desired one.
