 - Added protected copy constructors to options types (e.g. `ChatOptions`).

+- Updated `AIFunctionFactory.Create` to produce better default names for lambdas and local functions.
+- Fixed `AIJsonUtilities.DefaultOptions` to handle the built-in `[Experimental]` `AIContent` types, like `FunctionApprovalRequestContent`.
+- Fixed `ToChatResponse{Async}` to factor `ChatResponseUpdate.AuthorName` into message boundary detection.
+- Fixed `ToChatResponse{Async}` to not overwrite `ChatMessage/ChatResponse.CreatedAt` with older timestamps during coalescing.
 - Fixed `EmbeddingGeneratorOptions`/`SpeechToTextOptions` `Clone` methods to correctly copy all properties.
