Tauri CLI 2.10.x silently skips copying the frontendDist (desktop/dist/)
to gen/android/app/src/main/assets/ on Android builds. The WebView then
fails at runtime with "Asset not found: index.html".
After cargo tauri android build, check if index.html landed in the
Android assets folder. If not (the bug path), copy dist/ manually and
re-run ./gradlew assembleUniversalRelease. Gradle is incremental here
(no Java/Kotlin changed) so the extra pass takes < 30s.
