Workgroup lifecycle

To facilitate future historians in locating discussions related to the wg-cluster-mempool, a specific tag named wg-cluster-mempool::tag has been retroactively applied to all relevant discussions. This measure ensures that these discussions remain accessible and organized. Notably, this tag is restricted to admin access, preventing its application to future discussions by other users. Initially, there was an issue where the link to the wg-cluster-mempool::tag was not functioning correctly for anyone besides moderators. However, this problem has since been resolved, ensuring that the tag is now properly accessible.
