vukhanhtruong/mobile-traffic-interceptor- — reverse-engineered prompt

Build me a desktop app called Trafexia that lets me inspect web traffic from my phone while it is on the same network as my computer. I want to be able to start a local proxy, have the app generate and manage its own certificate for HTTPS interception, and show a really simple setup flow with a QR code plus clear steps for Android and iPhone.

Once traffic is coming in, show requests live in a polished dark interface. Let me filter by method, status, host, and content type, and click into any request to see headers, body, timing, and nicely highlighted content. It should also detect useful things like JWT tokens, API keys, and Base64 strings automatically. I also want export options for HAR, curl, Python, and Postman collections.

Please make it feel complete and easy to run locally, with the proxy on the usual port and sensible defaults. Look up current docs online if you need to.
