[findNextStep]

for example we have two file in project
test.h

void test_func();

test.cpp

#include <cstdio>
void test_func(){ printf("test\r\n");}

and the test_func is Invalid case style for function and we click quick fix only funcition name in test.h will be change, but it should change both in test.cpp and test.h

The current integration of clang-tidy and clangd doesn't really allow for this. The best solution for this would annoyingly involve creating a new version of the check that's based on clangds internal renaming mechanisms. Though it's still not a perfect solution

I'm going to forward-dupe this to #1589 which contains more detailed discussion of this issue (and there is work towards resolving it in llvm/llvm-project#78454).
