- Add info!-level tracing to workflow executor: logs each execution round, each step run (with type and name), step completion, and workflow completion - WorkflowHost.start() now auto-registers all built-in primitive step types so users don't need to register them manually - Add #[derive(Default)] to all primitive steps and PollEndpointConfig - Add tracing-subscriber to wfe crate for the pizza example - Pizza example now shows full step-by-step execution logs
