Fix cast issue

I simulated the automatic failover capability of the container module by randomly killing threads inside the container and discovered that the driver module has an infinite crash issue. The crash stack is as follows:

2025-09-24 15:02:22,569 [driver-executor-0] ERROR Driver:154  - driver exception
java.lang.ClassCastException: org.apache.geaflow.runtime.core.scheduler.PipelineCycleScheduler cannot be cast to org.apache.geaflow.runtime.core.scheduler.ExecutionGraphCycleScheduler
	at org.apache.geaflow.runtime.pipeline.runner.PipelineRunner.executePipelineGraph(PipelineRunner.java:80)
	at org.apache.geaflow.runtime.pipeline.runner.PipelineRunner.runPipelineGraph(PipelineRunner.java:87)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
	at java.lang.Thread.run(Thread.java:750)

The reason for the issue is that CycleSchedulerFactory.create() may return either a PipelineCycleScheduler type or an ExecutionGraphCycleScheduler type, but the code only accounts for the ExecutionGraphCycleScheduler scenario.

The CI check failure doesn't seem to be a code issue. Could we try retrying it? @cbqiao @yaozhongq
