 Currently, the WordPress Heartbeat API provides a reliable post locking
 mechanism for standard post types (e.g., post, page, article) where a
 postID is available. This prevents concurrent editing and ensures content
 integrity.

 However, this mechanism does not function correctly for Site Editor
 entities such as wp_template and wp_template_part. Since these are managed
 through the Site Editor and do not follow the traditional post editing
 flow, the default locking behavior fails, leading to potential conflicts
 when multiple users edit the same template simultaneously.

 This creates a gap in collaborative editing workflows, especially for
 teams working extensively with Full Site Editing (FSE).

 A custom solution has been identified to address this limitation by
 introducing a lock mechanism tailored for Site Editor entities. The
 proposed approach ensures:

 Proper identification and locking of wp_template and wp_template_part
 entities
 Prevention of simultaneous edits across multiple users
 Consistent behavior aligned with the existing Heartbeat-based locking
 system

 Further implementation details and validation of the solution can be
 provided.
