Remove -Weverything flag

> Since `-Weverything` enables every diagnostic, we generally don’t
> recommend using it. `-Wall -Wextra` are a better choice for most projects.
> Using `-Weverything` means that updating your compiler is more difficult
> because you’re exposed to experimental diagnostics which might be of
> lower quality than the default ones.
