[FEATURE] 目前的长期记忆机制不够好用，希望能有自动化的长期记忆机制

Feature Description The current long-term memory mechanism is implemented through a variable system, which requires developers to maintain it manually. We hope to have an automated, one-click long-term memory mechanism that is more user-friendly and easier to use. Refer to the following usage descriptions: The Agent platform supports the activation of long-term memory capabilities. After activation, the agent will actively identify and extract user personalized information in multiple rounds of dialogue and record it. It also supports user-defined prompts for customizing the extraction logic of memory segments. Clicking on the Personalization option will enable the agent to actively identify and extract user personalized information in subsequent rounds of dialogue. Checking the reference to the history chat records will also update preferences based on dialogue history facts. The prompt set through the memory management function is used to customize the extraction logic of memory segments.
