Fix text selectable node crash

- Guard AccessibilityNodeInfo.isTextSelectable behind the API 33 runtime check so Android 12 devices do not crash while classifying nodes
- Preserve text-selectable capability reporting on supported Android versions with a defensive fallback for OEM framework issues
- Add classifier coverage for text-selectable facts so capability propagation stays covered
