### Task Summary This issue adds the backend support needed to safely restart a workflow region after it has already completed or been terminated. Currently, the region execution state and control-channel state assume that a region runs only once. For control-flow execution, a region may need to run multiple times, so the system must clean up stale execution/gateway state and allow the same region to be reinitialized. Scope: - Allow WorkflowExecution to reinitialize a region execution. - Clean up input/output control-channel state when region workers are terminated. - Expose input/output gateways through AsyncRPCClient so termination cleanup can remove stale channels. - Make operator-port result URI insertion idempotent for repeated region runs. - Add tests covering control-channel cleanup and duplicate result URI insertion. ### Priority P2 – Medium ### Task Type - [x] Code Implementation - [ ] Documentation - [ ] Refactor / Cleanup - [ ] Testing / QA - [ ] DevOps / Deployment -- This is an automated message from the Apache Git Service.
