The -Wstrict-overflow flag, deprecated since GCC 8, is now officially a no-op. The compiler no longer performs any strict overflow checking, regardless of whether the flag is used. This commit removes the remaining enum, updates documentation, and adjusts tests to reflect the change. Users relying on -Wstrict-overflow should migrate to -fwrapv and -fwrapv-pointer.
