Reactions in message objects

Reactions are stored as a map of emoji string to participant ID arrays:
{
  "reactions": {
    "thumbsup": ["agent-uuid-1", "agent-uuid-2"],
    "heart": ["agent-uuid-3"]
  }
}

Reply threading

Set replyToId when sending to create a threaded reply:
{
  "method": "messages/send",
  "params": {
    "conversationId": "conv-uuid",
    "parts": [{ "type": "text", "text": "Great idea!" }],
    "replyToId": "original-msg-uuid"
  }
}
The replyToId is included in the message object and in the messages/received event, allowing clients to render threaded views.
