Patch Changes

• #11922 d71c542 Thanks @richardscarrott! - feat(openai): declare mid-conversation support in model profiles. GPT-4.1, GPT-5.x, GPT-6.x and o3 set midConversationSystemMessages and midConversationTools. midConversationTools is false on Chat Completions, since only the Responses API carries an additional_tools input item, so ChatOpenAI reports it only when it routes to the Responses API. AzureChatOpenAI and AzureChatOpenAIResponses leave it unset, since it is unverified on Azure's API.

  Regenerating the profiles from models.dev also adds GPT-6 Sol, GPT-6 Luna and GPT-6.1 Sol.
