Kntnt user_nicename from display_name

This is a plugin for sites built with the popular CMS that modifies how author archive page URLs are generated. It's designed for site administrators who want cleaner, more professional author links that reflect public display names instead of internal login usernames.

Display Name URLs: Automatically sets the user_nicename field, which forms the author page slug, based on the user's chosen display name. Improved Consistency: Ensures author page URLs are readable and consistent with the public-facing name, avoiding awkward or unprofessional links derived from login credentials. Simple Activation: Functions as a 'must-use' plugin; place the single file in the mu-plugins directory to apply the change site-wide. Profile Update Required: After installation, each user profile must be saved once to trigger the update of their specific author slug. Backward Compatibility: Works with existing author pages; updating a profile applies the new slug rules for that user.
