RTC: [Transport] Clean up old sync messages on stale sessions #75311
Description
Implementation Plan: Cron-based cleanup of stale RTC post meta
Introduce a cron task or other mechanism to clean up sync messages left behind by the real-time collaboration default provider, which are stored in post meta against a special post type.
Approach
- A daily WP-Cron event (wp_sync_cleanup) queries for sync updates older than n days.
- Each sync update value is an associative array envelope with a
timestampproperty. - If the sync update older than the expiration period, the post meta is deleted.
- The expiration defaults to 7 days and is configurable via the wp_sync_cleanup_expiration filter.

The work being done in core to convert to table based storage will likely make this issue redundant.
