📄 Description

Update memory middleware to use SystemMessage class instead of string-based systemPrompt. This change aligns the middleware with the updated request interface. (request.systemPrompt seems to be deprecated)

  • Replace systemPrompt string with SystemMessage object
  • Use SystemMessage.concat() method for combining memory section with existing system message
  • Update all test cases to use SystemMessage constructor and .text property for assertions
