chat.room.message.created v1 (OpenVibe.Chat server/rooms/rooms.js post, WS-I task 9). A message was posted in a PUBLIC chat room, so it reaches the realtime plane (browsers subscribed to chat.room.*). Private rooms and DMs never emit it: they stay on Chat's own WebSocket. Envelope: subject { type: chat_room_message, id }, visibility public, actor the author (user). Written in the transaction that stores the message; chat.room.message.deleted redacts it.
