DpCoordinatorActor — one cluster-singleton per model. Doc §4, §6.1.
Holds the routing CRDT (deployment-name → engine-core endpoints
with load scores) and answers RouteTo asks from RequestActors.
The implementation is a thin in-process map for v0; a real cluster
deployment registers this actor with
rakka_cluster_tools::ClusterSingletonManager so there’s exactly
one per (model, cluster).
