Extract a PresencePort seam (async setFocus/clearSocket/isViewing) with two impls: the existing in-memory Map (dev, single instance) and a new RedisPresenceService (prod). MessageModule provides PRESENCE_PORT via a REDIS_URL-gated factory — same pattern as the socket.io Redis adapter — so 'who is viewing what' is shared across replicas and the notification projector's presence gate works at N>1. Gateway + projector inject the port; isViewing is now awaited. Presence spec updated to async (passing). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
