Build me an app that lets me control and monitor command-line coding agents like Claude Code or Codex from anywhere. I want to be able to start an AI session on my desktop and then check on it using a mobile app (for both iOS and Android) or a web client.

The main thing is I need to see the real-time output from the agent on my phone and be able to send it commands. It should also send me push notifications if the AI gets stuck or needs my input. Make it really easy to switch control between my phone and my desktop—like, if I'm back at my computer, I should just be able to press any key to take over the session again.

Security is important, so all the communication between my desktop and the remote clients must be end-to-end encrypted. You can build the mobile apps with something like Expo or React Native, and use TypeScript for the whole project.
