Summary

Deliver @suaveplan/network-trystero-server on the genesis branch from scratch at enterprise quality. Trystero enables serverless WebRTC mesh networking using public signalling infrastructure (BitTorrent DHT, Nostr, Firebase, MQTT, Supabase). This server-side package provides a Node.js host that can act as a persistent relay peer within a Trystero room — bridging browser peers, relaying data, and optionally recording room state. It wraps Trystero's joinRoom API into a typed TrysteroServerAdapter with room lifecycle, peer events, typed data channels, and full OTel observability.

Impact

Downstream: browser-to-server WebRTC bridge, real-time multiplayer relay. Requires Node.js and network access for integration tests.

Prerequisites on Verdaccio: @suaveplan/error, @suaveplan/types, @suaveplan/events, @suaveplan/logger.
