/**
 * UDSClient — owner-side IPC socket client (Unix Domain Socket / Named Pipe).
 *
 * The counterpart of UDSServer: connects to a hub, speaks the length-prefixed
 * MessagePack wire format, and emits decoded NamespacedMessages. Connection
 * retry is built in so a session host can outlive hub restarts.
 *
 * This is transport plumbing only — handshake, announcements, and session
 * semantics live in IPCSessionHost.
