Research direction
Start with the Cirrus CI task and the failing DefaultContSpec test, then inspect the stack locations in Runners.scala, WorkStealingThreadPool.scala, and WorkerThread.scala. Reproduce the timeout on JVM Apple Silicon and trace the cancellation path; done means the get-can-be-canceled test completes reliably on that platform.
