Contributions summary:Emmett primarily focused on refactoring and renaming components within the Pub/Sub API. Their work involved removing redundant mentions of "event bus" and updating the codebase to use "pubsubapi" consistently. These changes were implemented by modifying the protobuf definition file and adjusting the service name. This refactoring streamlines the API's internal logic, making it easier to maintain.
