Note

Adds an AllowNoPollers option to worker deployment client ops and passes it through to server requests, with new tests and a dev server version bump.

• Worker Deployment Client:
  • Add AllowNoPollers to WorkerDeploymentSetCurrentVersionOptions and WorkerDeploymentSetRampingVersionOptions.
  • Pass AllowNoPollers in SetWorkerDeploymentCurrentVersionRequest and SetWorkerDeploymentRampingVersionRequest.
• Tests:
  • Add TestRampVersion_AllowNoPollers and TestCurrentVersion_AllowNoPollers to validate behavior when no pollers exist.
• Dev tooling:
  • Bump dev server cached version in internal/cmd/build/main.go to v1.5.0-rc.
