* migrated a lot of unit tests to Swift Testing and added a new implementation for deferred fulfillment more tests migration Cleaned the code manually to establish some good patterns more code improvements some more code improvements removed empty tests update project * more pr suggestions and cleanups * removed the TestSetup pattern * fixing claude not reusing tests * pr suggestion + added indent rule to swiftformat so that we can prevent AIs to change that
