When a workflow is terminated or times out, dispatch cancel commands to workers for in-flight activities that registered a control queue. Extends the mechanism from #9233 to cover forceful workflow close scenarios (including reset, which terminates the old run). Guarded by EnableCancelActivityWorkerCommand. Disabled by default.

Cancel commands for in-flight activities are now generated from GenerateWorkflowCloseTasks instead of being called explicitly from TerminateWorkflow and TimeoutWorkflow. This covers all workflow close paths (complete, fail, timeout, cancel, terminate, continue-as-new) with a single call site. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Cancel commands are best-effort and only dispatched on the active cluster. Avoid creating tasks on standby that will be immediately dropped by the outbound executor. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

What
On workflow close, dispatch cancel-commands to workers for in-flight activities. Extends the mechanism from #9233 to cover all workflow close paths.
Cancel command generation lives in
GenerateWorkflowCloseTasks, which is called from every close path (complete, fail, timeout, cancel, terminate, continue-as-new). Guarded byEnableCancelActivityWorkerCommand(disabled).Why
Previously, workers only discovered workflow termination/timeout passively via heartbeat (
NOT_FOUND) or when completing the activity. If heartbeat isn't enabled, activities run to completion uselessly.How did you test it?
