Build me an iPhone security tweak for jailbroken devices that helps protect against nasty WebKit and iMessage zero click exploits.

I want it to work on modern iOS versions, with both a jailbreak version and a TrollStore dylib version if possible. The app should let me turn on different protection levels for Safari, Messages, Mail, and other apps, like blocking JIT and risky JavaScript behavior, spoofing the user agent, stopping remote content and auto downloads, reducing web features like WebRTC and WebGL, and preventing dangerous attachment previews.

It should also have a simple settings screen, an easy way to quickly enable protections inside an app, and some kind of stronger mode for protecting system services and daemons. If you need to check current docs or behavior for iOS internals, look them up online as you go.
