Use Tool Calls

Add standard tools and tool_choice fields to a Chat Completions request:

{
  "model": "dari/routing",
  "messages": [{"role": "user", "content": "What is the weather?"}],
  "tools": [
    {
      "type": "function",
      "function": {
        "name": "get_weather",
        "parameters": {"type": "object", "properties": {}}
      }
    }
  ]
}

If the selected model calls a tool, its assistant message contains tool_calls. Run the tool, append its result as a tool message, and send the full message history again.
