Key features:

1. Automatic name initialization: Sets _name in storage from ctx.id.name if not already set
2. Registry table creation: Creates _do_registry table in the _registry instance
3. Automatic registry updates: Uses ctx.waitUntil to update registry on every fetch
4. Database size tracking: Uses storage.sql.databaseSize for size reporting
5. RPC communication: Registry instance handles /update and /registry endpoints
6. Error handling: Graceful error handling with logging

The decorator automatically:

• Initializes the name on first request
• Updates the registry with current database size
• Handles registry operations for the special _registry instance
• Provides access to the name through this.nameable.getName()
