RealtimeBackplanePlugin(options?: RealtimeBackplanePluginOptions): IPlugin
Creates the RealtimeBackplanePlugin.
Registers a transport under CAPABILITIES.REALTIME_BACKPLANE, which the
WebSocket and SSE plugins resolve optionally — so adding this plugin is
what turns their in-process rooms and channels into cluster-wide ones, and
removing it returns them to in-process behavior with no code change.
Its priority is above normal so the transport is connected before the consumers register and subscribe.
