Dimension	Assessment	Rationale
Change confidence	9.5/10	Generated code and vendored proto only; no worker behavior changes. go build, go vet, and go test ./... pass locally. DTS emulator E2E tests skipped locally and run in CI.

Summary

This PR refreshes the vendored orchestrator_service.proto to microsoft/durabletask-protobuf@2dab0e7 (microsoft/durabletask-protobuf#83) and regenerates the Go bindings.

It is the first step for extended sessions in the Go worker. The worker doesn't use the new RPCs yet, so behavior doesn't change.

Changes

• vendored/durabletask-protobuf: updated with update-proto.sh. The new contract adds:
  • CompleteOrchestratorTaskWithExtendedSession and CompleteEntityTaskWithExtendedSession (server streaming)
  • ReleaseTaskOrchestratorWorkItem and ReleaseTaskEntityWorkItem
  • completionCount on OrchestratorResponse and EntityBatchResult
  • CompleteTaskWithExtendedSessionResponse, ExtendedSessionAck, and ReleaseTaskWorkItemRequest/Response
  • tags on StartNewOrchestrationAction (from Add tags to entity-scheduled orchestration actions durabletask-protobuf#80)
• internal/protos: regenerated with the CI-pinned protoc-gen-go v1.36.12 and protoc-gen-go-grpc v1.6.2.
• CHANGELOG.md: one entry under Unreleased.

Validation

• go build ./..., go vet ./..., and go test ./... -count=1 pass locally.
