* Fix Cluster Sharding private replicator recovery Watch role-scoped sharding DData replicators and recreate them at their stable actor paths when they terminate. Use actor selections so existing coordinators and remember-entities stores continue communicating with the replacement incarnation. Add regression coverage for DData remember entities and the persistence compatibility configuration. * Address sharding replicator recovery review Keep IActorRef throughout the sharding DData consumers and publish a local replacement message when the guardian recreates a terminated replicator. Existing coordinators and remember-entities stores swap to the new ref and retry their active operation, while providers use the replacement for newly-created stores. Use WatchWith role-aware termination messages, preserve the peer-visible actor path, suppress shutdown recreation, and simplify the regression test fixtures. * Simplify remember entities provider tracking * Simplify sharding replicator recovery * Cover sharding replicator coordinated shutdown
