- New internal/temporal/poimen.go: PoimenHandler with typed REST endpoints
POST /v1/poimen/plan — call PlannerActivity (stub until workflows#23)
POST /v1/poimen/execute — start DAG/Orchestrator/Routing workflows
GET /v1/poimen/executions — list Poimen workflow executions
GET /v1/poimen/executions/:id — describe execution
GET /v1/poimen/executions/:id/history — activity event history
GET /v1/poimen/executions/:id/stream — SSE events (delegates to sse.go)
POST /v1/poimen/executions/:id/signal — pause/resume/cancel
DELETE /v1/poimen/executions/:id — terminate workflow
- New internal/serviceadapter/poimen_adapter.go: ServiceAdapter spec + factory
- Wire PoimenHandler in cmd/gateway/main.go via ServiceAdapter registry
- Workflow type registry: dag->DAGWorkflow, orchestrator->OrchestratorWorkflow,
routing->RoutingWorkflow (all on poimen-worker task queue)
