Workflow 2.2.11 fixes an early durable timer wakeup in poll mode. If a queue transport delivers a timer job before its durable deadline, the runtime now queues another bounded wakeup. This also covers timers whose transport delay is capped for long waits.
The patch keeps ordinary poll-mode workflow and activity tasks on external polling. It does not change the public SDK protocol.
