v6.1.4
$request->files->all() returns raw Symfony UploadedFile instances, which fail the `Illuminate\Http\UploadedFile` type hint in normalizeFile() — PHP 8 throws a TypeError, caught silently as "file metadata unavailable". Switched to $request->allFiles() which runs
Laravel's convertUploadedFiles() conversion, wrapping Symfony instances in their Illuminate counterparts before normalization. Added a
regression test that seeds the FileBag with a raw Symfony UploadedFile to prevent this from regressing.
