e2e tests for #1354

Fixes #1349. This commit addresses the issue where `run.getReadable()`/`run.readable` do not properly propagate cancellation on disconnect. It implements the `cancel(reason)` method on `WorkflowServerReadableStream` to ensure it delegates cancellation to its inner reader. Additionally, this ensures that `flushablePipe` properly propagates the cancellation to the source stream instead of only releasing locks, thereby cleaning up listeners.
