context.cancel

All of the methods covered so far are used to define workflow steps.

context.cancel is different — it allows you to explicitly cancel the current workflow run.

export const { POST } = serve<{ topic: string }>(async (context) => {  const payload = context.requestPayload  const result = await context.run("check if canceled", () => { ... });  if (result.cancel) {    await context.cancel() // cancel the workflow run  }})

When a workflow run is canceled:

• It is labeled as canceled (not failed).
• The configured failureFunction is not triggered.
• No entries are sent to the dead-letter queue (DLQ).
