IndexGenerator output order depends on OS locale (cs vs en)

Package version

8.5.x

Describe the bug

IndexGenerator sorts scanned files with naturalSort from @poppinss/utils (see: virtual_file_system.ts ). That helper creates Intl.Collator without a locale (see: poppinss natural_sort ), so Node uses the OS/ICU default locale.

Generated files such as:

• .adonisjs/server/controllers.ts
• .adonisjs/server/pages.d.ts

therefore get a different key/path order depending on the developer's system language.

Slice of the pages.d.ts file on system with Czech (cs) language:

    'admin/auth/login': ExtractProps<(typeof import('../../inertia/pages/admin/auth/login.tsx'))['default']>
    'admin/groups/index': ExtractProps<(typeof import('../../inertia/pages/admin/groups/index.tsx'))['default']>
    'admin/groups/show': ExtractProps<(typeof import('../../inertia/pages/admin/groups/show.tsx'))['default']>
    'admin/children/index': ExtractProps<(typeof import('../../inertia/pages/admin/children/index.tsx'))['default']>
    'admin/children/show': ExtractProps<(typeof import('../../inertia/pages/admin/children/show.tsx'))['default']>
    'admin/users/index': ExtractProps<(typeof import('../../inertia/pages/admin/users/index.tsx'))['default']>
    'admin/users/show': ExtractProps<(typeof import('../../inertia/pages/admin/users/show.tsx'))['default']>

Slice of the pages.d.ts file on system with English (en) language:

    'admin/auth/login': ExtractProps<(typeof import('../../inertia/pages/admin/auth/login.tsx'))['default']>
    'admin/children/index': ExtractProps<(typeof import('../../inertia/pages/admin/children/index.tsx'))['default']>
    'admin/children/show': ExtractProps<(typeof import('../../inertia/pages/admin/children/show.tsx'))['default']>
    'admin/groups/index': ExtractProps<(typeof import('../../inertia/pages/admin/groups/index.tsx'))['default']>
    'admin/groups/show': ExtractProps<(typeof import('../../inertia/pages/admin/groups/show.tsx'))['default']>
    'admin/users/index': ExtractProps<(typeof import('../../inertia/pages/admin/users/index.tsx'))['default']>
    'admin/users/show': ExtractProps<(typeof import('../../inertia/pages/admin/users/show.tsx'))['default']>

Adonis docs recommend committing these generated files. In a team where one developer uses cs and another en, regenerating the files produces noisy git diffs even though nothing in the app changed.

Suggested fix

Generated artifacts should be sorted with an explicit, stable locale (e.g. 'en'), for example:

const collator = new Intl.Collator('en', {
    numeric: true,
    sensitivity: 'base',
});
const sortedFiles = filesList.sort(collator.compare)

Alternatively, @poppinss/utils naturalSort could default to 'en' (or accept a locale argument).

Either way, assembler-generated files that are meant to be committed should not depend on Intl default locale.

Reproduction repo

No response

Start in src/virtual_file_system.ts at the IndexGenerator file sorting around line 111, then inspect the linked @poppinss/utils naturalSort implementation. Reproduce generation under Czech and English locales and determine the smallest stable-locale change; done means generated paths have the same order regardless of OS locale and the relevant behavior is covered by tests.
