It might be worth updating the documentation as well...?

Thanks @fmuyassarov for this. Looks good and makes sense to me

It might be worth updating the documentation as well...?

Yes, I don't remember if it's somewhere else (likely not) but at least the customization guide probably needs some update

Pull Request Overview

This PR implements support for unprefixed annotations through a feature gate mechanism, allowing users to control whether annotations are automatically prefixed with the NFD namespace. When the DisableAutoPrefix feature gate is enabled, unprefixed annotations are allowed without automatic prefixing.

• Adds conditional logic to skip auto-prefixing when the DisableAutoPrefix feature gate is enabled
• Updates annotation filtering to allow unprefixed annotations when the feature gate is active
• Expands test coverage to verify both prefixed and unprefixed annotation behavior
