Previously, the Rails application would reload due to changes
in some files outside the autoload paths.
For instance, editing `app/README.md` would trigger a reload,
even though the reloaded classes and modules were identical
to those loaded previously.

This commit fixes this issue by ensuring the application reloads correctly
according to `Rails.autoloaders.main.dirs`, thereby preventing unnecessary reloads.
