WebSocket hub for real-time streaming in Go. Implements the hub pattern with centralised connection management, named channel pub/sub, token-based authentication on upgrade, client-side reconnection with exponential backoff, and a Redis pub/sub bridge for coordinating broadcasts across multiple hub instances. The envelope pattern with a per-bridge source ID prevents loop amplification when the Redis bridge is in use.
