[Feature Request] Demonstrate retries in worker-specific-task-queue sample

[cretz]

Describe the solution you'd like

Users need to see how to retry whole set of things in the sample if, say, worker crashes

Hi maintainers, I’d like to take this on sequentially after the sample work already discussed in #103 and #104. My proposed approach is to extend worker_specific_task_queues with an explicit recovery path that retries the worker-local operation sequence after worker loss, documents the retry semantics, and adds a failure/restart test. Could you confirm that this is the intended scope, rather than retrying only an individual Activity? If so, could you please assign the issue to me? For context, my earlier contribution #343 has been reviewed and merged. Thanks!
