Add Chinese meta files for protocol references

Added Chinese meta.json files for AI, API, Auth, Automation, Data, Driver, Permission, System, and UI protocol references. Removed the integration meta.json file and updated system/meta.json and ui/meta.json by removing the 'root' property. This improves localization and maintains consistency across documentation.
