Fix workflow script syntax and Android build warnings

- Consolidated multi-line bash script to avoid shell syntax errors
- Removed deprecated package attribute from AndroidManifest.xml
- Removed uses-sdk element (minSdkVersion managed in build.gradle.kts)
- Removed android:extractNativeLibs attribute
- Removed unused context variable from MainActivity.kt

All Android manifest attributes are now properly managed in build.gradle.kts
following modern Android development practices.
