GroupManagementInterface

What it does

This interface defines methods for managing and retrieving customer groups in Magento 2.

Developers use it to access default groups, check if a group can be deleted, get logged-in/not-logged-in groups, and retrieve the special 'all customers' group.

It's commonly used in pricing rules, promotions, and access control features that need to differentiate customer types.
