/**
 * Cross-Agent Intelligence Protocol — the hub that makes all coding agents talk to each other.
 *
 * Transport:
 *   Primary: WebSocket on port 7344 (CAIP bus)
 *   Fallback: Shared filesystem at ~/.shadow-brain-caip/ (polling every 2s)
 *
 * Protocol:
 *   1. Handshake — each agent sends identity, version, capabilities
 *   2. Channels — broadcast (all), pair (two agents), team (subset)
 *   3. Boost Packet — high-value insight shared to all connected agents
 *   4. Deduplication — message hash ring prevents infinite loops
