fix: lower minSdk to 26 for broader Android device compatibility
- Changed minSdk from 31 (Android 12) to 26 (Android 8.0) - This allows installation on devices running Android 8.0+ - Gemini Nano features will gracefully degrade on older devices - Fixes APK installation failure on devices below Android 12
