-
-- Health checks are now properly registered for both journal and snapshot store
-- Snapshot store health check support added via `Action&lt;AkkaPersistenceSnapshotBuilder&gt;` parameters
-- Migrated from manual HOCON manipulation to the unified Akka.Hosting API (`.WithJournal()` and `.WithSnapshot()`)
