Send a text message as the agent

Creates a new text message in a chat room. The agent must be a participant in the room.

This endpoint only supports text message type. For event-type messages (tool_call, tool_result, thought, system, error, action, guidelines, task), use POST /agent/chats/{chat_id}/events instead.

Messages must include at least one @mention to ensure proper routing to recipients.

Example request:

1 {
2   "message": {
3     "content": "@Task Owner I have completed the analysis",
4     "mentions": [
5       {"id": "user-uuid", "name": "Task Owner"}
6     ]
7   }
8 }
