Exposes the EnableCancelWorkerPollsOnShutdown dynamic config as a namespace capability. This allows SDKs to check whether the server supports server-side poll completion on shutdown before relying on it. Depends on: temporalio/api#719 (proto changes)

This capability indicates whether the server supports server-side completion of outstanding worker polls on shutdown. When enabled, the server will complete polls for workers that send WorkerInstanceKey in their poll requests and call ShutdownWorker with the same key.

## What Changed Exposes the `EnableCancelWorkerPollsOnShutdown` dynamic config as a namespace capability in `DescribeNamespace` response. ## Why SDKs need to know whether the server supports server-side poll completion on shutdown before relying on it. This capability allows SDKs to check via `DescribeNamespace` and decide: - If `true`: Send `WorkerInstanceKey` in polls and rely on server to complete polls on shutdown - If `false`: Handle poll completion client-side (existing behavior) ## How - `service/frontend/namespace_handler.go`: Added `WorkerPollCompleteOnShutdown` to capabilities - `service/frontend/namespace_handler_test.go`: Added test coverage for the new capability ## Dependencies - Bumped `go.temporal.io/api` to `v1.62.2-0.20260213194545-c89ebac64f01` to include new proto field from temporalio/api#719
