Tencent/matrix ? reverse-engineered prompt

Build me a plugin style performance monitoring toolkit for mobile apps like the one WeChat uses. I want it to work on iOS, macOS, and Android, and let an app turn on different monitors from one place at startup.

It should be able to track crashes, app freezes, memory problems, slow screens, startup issues, UI blocking, ANR, file IO problems, SQLite issues, battery related problems, and common APK size checks on Android. For iOS and macOS, include crash and lag monitoring, memory tracking, and FPS monitoring. Make it easy to plug into an app with minimal code, and provide callbacks so the app can receive reported issues in a structured way.

Also include a simple sample app or demo showing how to start the monitors and view the collected data. Keep it clean and practical, and if you need current setup details or platform docs, look them up online before finishing.
