Reflect durabletask-protobuf#29: update submodule and regenerate protos

[Copilot]

Mirrors the changes from dapr/durabletask-protobuf#29 by updating the protobuf submodule to that PR's branch and regenerating all Go proto files from the actual new proto definitions, then updating the codebase accordingly.

Submodule

• submodules/durabletask-protobuf updated to commit 0d06f73 on branch copilot/rename-protos-to-workflow
• .gitmodules updated to track that branch

Regenerated proto files

The old monolithic orchestrator_service.proto is split into focused files. Old generated files removed:

• orchestrator_service.pb.go
• orchestrator_service_grpc.pb.go

New generated files added:

• workflow_messages.pb.go — WorkflowInstance, WorkflowStatus, WorkflowState, WorkflowVersion, WorkflowIdReusePolicy, core shared types
• history_events.pb.go — all HistoryEvent variants, SubWorkflowInstance*Event, WorkflowExecutorStartedEvent
• workflow_actions.pb.go — WorkflowAction, WorkflowRequest, WorkflowResponse, action types
• entity_messages.pb.go — entity operation messages
• workflow_service.pb.go + workflow_service_grpc.pb.go — TaskHubSidecarService

Regenerated with new type names:

• backend_service.pb.go / backend_service_grpc.pb.go — WorkflowMessage, WorkflowMetadata, CompleteWorkflowWorkItem*, AbandonWorkflowWorkItem*, GetWorkflowRuntimeState*, BackendWorkflowState, new Workflow*-named RPCs alongside deprecated Orchestration* ones; RPC path prefix updated to durabletask.protos.v1
• runtime_state.pb.go — WorkflowRuntimeState, WorkflowRuntimeStateMessage

Backward-compatible aliases (workflow_aliases.go)

Rewritten to map old Orchestration*/Orchestrator* names to the new canonical Workflow* types now defined in the generated code:

type OrchestrationInstance = WorkflowInstance
type OrchestrationStatus   = WorkflowStatus
type OrchestratorAction    = WorkflowAction
type OrchestratorRequest   = WorkflowRequest
type OrchestratorResponse  = WorkflowResponse
// ... all Orchestration*/Orchestrator* aliases

// Deprecated enum constant aliases
OrchestrationStatus_ORCHESTRATION_STATUS_RUNNING = WorkflowStatus_WORKFLOW_STATUS_RUNNING
// ... all ORCHESTRATION_STATUS_* → WORKFLOW_STATUS_* aliases

// Oneof type aliases
OrchestratorAction_CompleteOrchestration = WorkflowAction_CompleteWorkflow
// etc.

Codebase updates

All non-generated source and test files updated to use new field/method names from the regenerated protos:

• es.OrchestrationInstance → es.WorkflowInstance
• e.GetOrchestratorStarted() → e.GetWorkflowExecutorStarted()
• e.GetSubOrchestrationInstance*() → e.GetSubWorkflowInstance*()
• resp.OrchestrationState → resp.WorkflowState
• state.OrchestrationStatus field → state.WorkflowStatus
• Struct literals updated to use new oneof types (WorkflowAction_CompleteWorkflow, WorkflowAction_CreateSubWorkflow, etc.)

dapr/dapr compatibility

Backward-compat aliases ensure existing dapr/dapr code continues to compile unchanged: backend.OrchestrationMetadata, backend.OrchestrationRuntimeState, protos.OrchestratorRequest/Response, protos.OrchestrationInstance, protos.OrchestrationVersion, runtimestate.NewOrchestrationRuntimeState(), etc. all remain valid.

Update the protos to use that PR and update the codebase accordingly

Update the protos to use that PR and update the codebase accordingly

Done in commit e96a4bf. Updated submodules/durabletask-protobuf to point to the copilot/rename-protos-to-workflow branch (commit 0d06f73) and regenerated all Go proto files from the new proto definitions. The old orchestrator_service.pb.go is replaced by the split files (workflow_messages.pb.go, history_events.pb.go, workflow_actions.pb.go, entity_messages.pb.go, workflow_service.pb.go). All non-generated source and test files updated to use the new field/method names. Backward-compat aliases for Orchestration*/Orchestrator* names are provided in workflow_aliases.go.
