Thanks @robertcoltheart !

Replace the hand-written parameterless WasCalled() extension with a [GenerateAssertion]-decorated method, per the project's preference for generated assertions. The previous manual overload targeted IAssertionSource<ICallVerification> directly, which does not bind to the concrete IAssertionSource<TMockCall> produced by Assert.That(mock.Method()) (IAssertionSource is invariant), so the WasCalled() call site did not compile. The generated covariant form WasCalled<TActual>(this IAssertionSource<TActual>) where TActual : ICallVerification binds correctly. - Declare the source method as a non-extension static so the generator emits a static-qualified call, avoiding the name clash with the void ICallVerification.WasCalled() instance method. - Reference TUnit.Assertions.SourceGenerator as an analyzer (it does not flow transitively through the TUnit.Assertions project reference). - Add a failing-path test for the parameterless WasCalled().
