📚 Description

Resolves #2151
Resolves #2182

The core of these issues seems to be that defineI18nLocale or defineI18nConfig are only removed once, but with autoImport disabled a file will usually contain the string multiple times.

This happened with autoImport disabled.

import { } from "#i18n";
export default defineI18nConfig(() => ({}));

My change results in:

import { } from "#i18n";
export default (() => ({}));

Which still looks odd but seems to work fine!
