Description

Fills the JS engine's consumer-rules.pro, which the engine already ships to apps. The native engine finds its Java classes by name through JNI, so with R8 on the app aborts at startup with ClassNotFoundException: io.ionic.android_js_engine.NativeWebAPI.

The rule keeps the engine's own package. Native code uses 12 of its 15 classes, so a narrower rule wouldn't save much.

Tested on Capacitor 8.5.3 with R8 on and the engine built from this branch. Events, JS errors, crypto, text encoding, KV, device, app, badge, timers and fetch all match R8 off, on an emulator and on a Pixel 11 Pro.

Logs

With main:

F DEBUG   : Abort message: 'terminating due to uncaught exception of type std::runtime_error: java.lang.ClassNotFoundException: io.ionic.android_js_engine.NativeWebAPI'

With this branch:

dispatchEvent("probeEvent") -> {"ok":true,"echoed":"N-BR"}

Notes

The engine AAR is rebuilt from source when the plugin is published, so the committed one isn't updated here. Capacitor 9 gets the same rule in a separate PR against next.
