The `<sys/stat.h>` include in `launcher.c` is only used to check if the executable is a symlink on macOS. Therefore it is not needed on other platforms.
Now there is only one launcher. Which means it can be used to start
kitty with profiling and ASAN in the natural way. The recommended
way to run kitty from source is now:
./kitty/launcher/kitty
The launcher also automatically re-execs to resolve symlinks on macOS.
