/**

* Tests for the queue-aware `Agent.cancel()` primitive. `cancel()` is the
|
||||
* broad verb — it clears queued + steering work, aborts an in-flight step, and
|
||||
* drops a turn about to start — whereas a bare step abort (the loop's private
|
||||
* `AbortController`) kills only the current step and leaves the queue intact.
|
||||
* These tests exercise every window where a cancel can land (idle, pre-step,
|
||||
* mid-step, continuation) and the marker's arm/reset rules that keep a cancel
|
||||
* from leaking to a later prompt or hanging `whenIdle()`.
