fix(i18n): make message extraction order deterministic

readdir file order can differ based on OS, causing extracted locale files to differ wherever
duplicate namespace/keys exist. this change sorts the file list with normalized path separators so
extraction output is byte-identical regardless of OS, which should prevent i18n check failures from
such collisions
