Skipping Middleware for steps like `If`, `While`, etc. prevents unnecessary operations

Middleware.cs

public class Middleware : IWorkflowStepMiddleware
{
    public async Task<ExecutionResult> HandleAsync(IStepExecutionContext context, IStepBody body, WorkflowStepDelegate next)
    {
        if (body is ContainerStepBody) return await next();
        Debug.WriteLine($"Start: {context.Step.Name ?? body.GetType().Name}");
        var result = await next();
        Debug.WriteLine($"End: {context.Step.Name ?? body.GetType().Name}");
        return result;
    }
}
