android: keyboard height tracking via JNI/FFI bridge
- C bridge (keyboard_bridge.c) stores keyboard state in globals.
Kotlin writes via JNI, Dart reads via FFI — zero async delay,
same architecture as iOS.
- WindowInsetsAnimation.Callback tracks open/close per-frame.
- OnGlobalLayoutListener catches silent height changes (emoji
keyboard resize, floating keyboard toggle).
- Dart animation replay stays iOS-only; Android reads native
per-frame values directly.
- Cleaned up old Java stub, updated build.gradle for Kotlin + CMake
with 16KB page alignment (Android 15+).
- Example app rewritten to demonstrate UxKeyboard usage.
