//! Distributed-node configuration.
//!
//! The `DistributedNode` orchestrator that once lived here has been retired:
//! SWIM membership, the cluster name registry, node-metadata dissemination, and
//! the actor→host directory now each run as an independent actor on the swactor
//! runtime — see [`crate::swim::actor`], [`crate::registry_actor`],
//! [`crate::node_metadata_actor`], and [`crate::directory_actor`]. Concrete
//! network drivers (for example `iroh-driver`) feed those actors. All that
//! remains here is the shared configuration bundle the node binary uses to
//! construct them.
