### What changes were proposed in this PR? Add `SchedulingUtilsSpec` covering the single public function `SchedulingUtils.replaceVertex` (`amber/src/main/scala/org/apache/texera/amber/engine/architecture/scheduling/SchedulingUtils.scala`), which rewrites a vertex (and its incident edges) in a JGraphT `DirectedAcyclicGraph[Region, RegionLink]`. Cases: - Isolated vertex with no incident edges - Outgoing edges are rewritten to originate from the new vertex - Incoming edges are rewritten to terminate at the new vertex - Chain-middle replacement preserves upstream and downstream edges - No-op when old and new vertices are equal ### Any related issues, documentation, discussions? Closes #4565 ### How was this PR tested? `sbt "WorkflowExecutionService/testOnly org.apache.texera.amber.engine.architecture.scheduling.SchedulingUtilsSpec"` — 5/5 tests pass. ### Was this PR authored or co-authored using generative AI tooling?
