Pass AbortSignal through workflow steps to cancel in-flight operations using standard web APIs, surviving durable suspension and replay.
Summary
Eliminates custom cancellation plumbing in long-running workflows. Developers can now timeout slow steps, race requests, and cancel parallel work using the same pattern as fetch, reducing boilerplate.

Implementation verdict
Replaces homegrown timeout/cancellation logic. Requires workflow@beta and explicit signal inspection in steps (cancellation is cooperative, not forced). Worth trying now if you're on Workflow SDK 5; covers common timeout and race patterns directly.
