The task
**Reproduction** 1. Configure an agent that triggers a tool call with a large arguments payload and streaming enabled (`stream: true`). 2. Observe the server emitting several `TOOL_CALL_ARGS` events, each carrying a portion of the arguments. 3. Inspect the final `tool_call_args` – it contains only the first chunk.
