Some files in `clang-tidy` like https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clang-tidy/readability/AvoidConstParamsInDecls.h are missing "Check" suffix in their filenames. We should add them (probably with a degree of automation) to keep codebase consistent. We could probably think about some linting to preserve such consistency.
