…handling# Performance Optimization: Add Transient Manager for Better Transient Handling

Description

This PR adds a new Transient Manager to improve the handling of transients in the plugin. The Transient Manager provides a centralized way to manage transients, making it easier to track, group, and clear them when needed. This improves performance by reducing the number of expired transients in the database and providing more control over transient lifecycle.

Changes Made

1. Added a new Transient_Manager class in inc/managers/class-transient-manager.php
2. Added helper functions in inc/functions/transients.php for easier transient management
3. Updated the main class to load the Transient Manager
4. Added support for transient grouping to allow selective clearing of transients
5. Added functions to register transients with the manager for better tracking

Benefits

• More efficient transient management
• Ability to group transients by functionality
• Easier clearing of specific transient groups
• Better tracking of transients used by the plugin
• Reduced database clutter from expired transients
• Improved performance for sites with many transients

Testing

1. Test setting and getting transients using the new functions
2. Verify that transients can be grouped and cleared by group
3. Check that all transients are properly registered with the manager

Performance Impact

• Before: Transients were managed individually without centralized tracking
• After: Transients are centrally managed, grouped, and can be selectively cleared

This optimization is particularly effective for sites with many transients, where selective clearing can significantly reduce database load.

I'm not sure what this is trying to do but I'm sure it doesn't work. The transient registry is not persisted so it will be empty most of the time. And wp_cache_add_non_persistent_groups() actually prevents the transients from being stored in redis or memcache so I'm sure that's not helpful.
