Summary of Changes

Hello @lloc, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on improving the user collection and selection process, particularly for the 'reference user' feature. It refactors the existing logic to centralize user count limitations and error handling within the MslsBlogCollection class, making the MslsAdmin class more focused on presentation. The changes also introduce a new filter for configuring the maximum number of reference users, enhancing flexibility and maintainability of the user management system.

Highlights

• Refactored User Collection in MslsAdmin: The reference_user() method in MslsAdmin.php has been refactored to streamline user fetching and filtering. It now uses wp_list_pluck for efficient data formatting and applies a new filter msls_max_reference_users_count to determine the maximum number of users.
• Centralized User Count Limitation: The logic for limiting the number of users and triggering an error when the count exceeds a maximum has been moved from MslsAdmin.php to MslsBlogCollection::get_users(). This centralizes the responsibility for user collection constraints.
• Enhanced MslsBlogCollection::get_users(): The get_users() method in MslsBlogCollection.php now explicitly accepts an integer for the user limit and issues a trigger_error if the total number of users found exceeds this limit, providing clearer error reporting.
• Updated Test Suite: The test suite has been updated to reflect these changes, including the removal of an outdated test for user truncation in TestMslsAdmin.php and the addition of a new test test_get_users_max() in TestMslsBlogCollection.php to verify the new user limitation error handling.

Code Review

This pull request refactors the logic for fetching and limiting the list of reference users. The responsibility is moved from MslsAdmin to MslsBlogCollection, which is a good architectural improvement. The use of wp_list_pluck in MslsAdmin is also a nice touch. However, I've found a significant performance issue in the new implementation within MslsBlogCollection that could lead to fetching all users from the database unnecessarily. The accompanying test changes are good but miss the specific case that would have caught this new bug.
