id in ToolCall missing

[randre70]

The id field in the tool_call is missing. The raw response (hook) contains the id (see below, "id": "call_p7o2gz50").
But the ToolCall class doesn't have this field nor is it in model_extra.

{
  "model": "...",
  "created_at": "2026-05-18T...",
  "message": {
    "role": "assistant",
    "content": " ",
    "tool_calls": [
      {
        "id": "call_p7o2gz50",
        "function": {
          "index": 0,
          "name": "test_function",
          "arguments": {
            "param1": "test1",
            "param2": 123
          }
        }
      }
    ]
  },
  "done": true,
  "done_reason": "stop",
  ...
}

I have to use a hook to extract the id from the raw response and keep it in a list of the same size as the response.message.tool_calls list.

I suggest the following patch:
