AgentX + Mistral AI Integration

Keep AgentX and Mistral AI aligned: when ai events happen in one, update the other automatically.

Example: when Mistral AI's "Watch Agents" fires, WEXTL can "Create Conversation" in AgentX. AgentX has 19 actions (including Create Conversation, Create Speech, and Create Speech Stream); Mistral AI has 72 actions (including Append Conversation, Archive Fine Tuned Model, and Cancel Batch Job).
