• #10143 62ba83e Thanks @topliceanurazvan! - fix(openai): emit handleLLMNewToken callback for usage chunk in Completions API streaming

  The final usage chunk in _streamResponseChunks was only yielded via the async generator but did not call runManager.handleLLMNewToken(). This meant callback-based consumers (e.g. LangGraph's StreamMessagesHandler) never received the usage_metadata chunk. Added the missing handleLLMNewToken call to match the behavior of the main streaming loop.
