to "true" on defaultArgoCDInstance before the create-or-update branch, ensuring
newly created GitopsService-managed ArgoCD instances are marked. Add a
reconciliation test that creates the ArgoCD, clears GitopsService placement, and

…goCD CR When GitopsService does not configure nodeSelector or tolerations, the reconcile loop was clearing spec.nodePlacement on the default ArgoCD CR. Admins who set nodePlacement directly on the ArgoCD CR (documented pattern for dedicated infra nodes) saw scheduling config removed every reconcile. Only sync NodePlacement when GitopsService explicitly configures placement fields. Track GitopsService-managed placement with an annotation so clearing GitopsService fields still removes operator-applied placement.

Set the managed-by annotation on defaultArgoCDInstance before create so clearing GitopsService placement later removes operator-applied placement for newly created instances too. Signed-off-by: Pratik Langde <plangde@redhat.com>

Summary
The GitopsService controller was clearing
spec.nodePlacementon the default ArgoCD CR whenever GitopsService did not configurenodeSelectorortolerations. Admins who setnodePlacementdirectly on the ArgoCD CR (documented OpenShift GitOps pattern for dedicated infra nodes) saw scheduling configuration removed on every reconcile, so Argo CD workloads never moved off default worker nodes.Root cause
In
reconcileDefaultArgoCDInstance, whendefaultArgoCDInstance.Spec.NodePlacementwas nil butexistingArgoCD.Spec.NodePlacementwas set, the controller unconditionally cleared NodePlacement — conflating "GitopsService has no placement config" with "remove all placement from ArgoCD CR".Fix
