fix: Add patch for Django issue #30479 - StatReloader doesn't track manage.py

Apply this patch to django/utils/autoreload.py to fix the regression where
changes to manage.py don't trigger autoreloader restart.

The fix adds special case handling for the __main__ module which has
__spec__ = None but still needs to be tracked for file changes.

Example usage:
  git apply django-autoreloader-30479.patch

django-autoreloader-30479.patch
