assay-engine 0.4.2

--! End-to-end test: client kicks a workflow that runs a real activity.
--!
--! Two-process design: a separate worker process (spawned by run.sh)
--! registers `demo.greet` + a `say_hello` activity and listens on the
--! `default` queue. This test starts the workflow, polls `describe`
--! until it reaches `COMPLETED`, then asserts the result.
