engenho-controllers 0.1.4

engenho-controllers — the engenho K8s controller suite. Hosts the Controller trait + canonical implementations: ReplicaSetController (R9), DeploymentController (R9.5), ServiceController (R9.6), GC (R9.7). Each is a thin reconcile loop on engenho-store. Same shape as engenho-scheduler — the second-site for the controller pattern.
