Suggestion:
lets rename the IsResourceChanged function to ShouldResourceBeRestarted. It will check if the the resouce has changed or is the pod was deleted due to eviction. The Sync function will just call the ShouldResourceBeRestarted, and if it returns true, it will delete the resource. WDYT?

- Around line 117-118: Update Sync’s DeleteResource error handling to return the
deletion error so restart retry handling is triggered, while preserving
successful completion when the resource is NotFound. Keep the existing failure
logging and use the established error semantics for distinguishing NotFound from
other deletion failures.

During a cluster upgrade, node drains can delete a Build's pod before it completes, leaving the Build in Error(BuildPodDeleted) forever since Sync() only recreated resources whose spec had changed. Detect this recoverable failure and delete the resource so it gets retried.
