clangd broke because it can't look through symlinks. compile_commands manipulation does not fix it, clangd configuration does not fix it, a vfs overlay does not fix it, and while a combination of those can fix it with a bind mount in place that's just too cursed to even consider clangd bug: https://github.com/llvm/llvm-project/issues/116877 Change-Id: I8e3e8489548eb3a7aa65ac9d12a5ec8abf814aec
