feat(android): expose semantics to the TalkBack screen reader

[mfazekas]

Bumps rive-android to 11.10.0 (adds accessibility semantics) and rive-ios to 6.24.0, and wires the semantics prop (Off / On / Automatic) on the Android new backend. iOS already supported all three modes; the legacy backends still ignore the prop. rive-ios 6.25.0 is tagged but not on CocoaPods trunk.

The SDK only offers semantics through its Compose composable, and its TalkBack host view is Kotlin-internal. RiveSemanticsTextureView.java reaches that host from Java, and RiveReactNativeView mirrors what the composable does on our own render loop (enable, drain after each advance, sync virtual nodes, route actions back, zero-delta frame while paused), copied from RiveSemanticsEffects / DrawRiveFramesEffect in Rive.kt @ 11.10.0.

rive-android needs androidx.core 1.17 (compileSdk 36). The example force-pinned 1.15 to stay on compileSdk 35, which crashed with NoSuchMethodError once semantics were enabled; the pin is removed and the example builds with compileSdk 36. Apps that keep such a pin now get an onError instead of a crash.

Verified on an emulator with tabtest.riv via uiautomator dump: On and Automatic expose the Child/Parent/All nodes with the correct selected state, Off removes them, Off → On re-enables without a remount. The iOS example builds and renders on 6.24.0.
