## What changed? <!-- Describe what has changed in this PR --> - Use VersionedTransition in StateMachineNode and Ref - Compare node last update failover version when syncing node. This is for addressing https://github.com/temporalio/temporal/pull/6145#discussion_r1646732338 - Fix mutable state failover version in Ref for task refresh case. Need to use last versioned transition, instead of currentVersion, which can be newer. ## Why? <!-- Tell your future self why have you made these changes --> ## How did you test it? <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> - New & existing tests. ## Potential risks <!-- Assuming the worst case, what can be broken when deploying this change to production? --> ## Documentation <!-- Have you made sure this change doesn't falsify anything currently stated in `docs/`? If significant new behavior is added, have you described that in `docs/`? --> ## Is hotfix candidate? <!-- Is this PR a hotfix candidate or does it require a notification to be sent to the broader community?
