When getNamespacesToList returns "" (cross-namespace listing), resources
from all namespaces are listed. The nsTracker.track call for each
resource's namespace would inadvertently track excluded namespaces,
causing their namespace objects to pass through filterNamespaces.
Add a ShouldInclude check before tracking a namespace from non-namespace
resources to ensure excluded namespaces are not tracked.
Add test case for includedNamespaces ["*"] with excludedNamespaces to
verify both the namespace object exclusion and resource exclusion.
