### What changes were proposed in this PR? This PR adds a generic scheduler primitive that allows workflow execution to jump back to the region containing a specified target operator. This is intended as the first step toward control-flow support. The implementation is kept generic and does not include loop-operator logic or region restart support. - Add `JumpToOperatorRequest` and `JumpToOperator` controller RPC. - Add `JumpToOperatorHandler` on the controller side. - Add scheduler/coordinator support for moving the schedule pointer to the region containing `targetOperatorId`. - Add a unit test for `Schedule.jumpToOperator`. ### Any related issues, documentation, discussions? Closes #4443 ### How was this PR tested? New test case introduced: sbt "WorkflowCore/clean" "WorkflowExecutionService/testOnly org.apache.texera.amber.engine.architecture.scheduling.ScheduleSpec" ### Was this PR authored or co-authored using generative AI tooling?
