Fix vertical overflow by removing nested Scaffold architecture

- Remove nested Scaffold from ScoringPage (now uses LayoutBuilder)
- Use proper constraint-based height calculation instead of MediaQuery
- Maintain score preservation across navigation without nested scaffolds
- Fix viewport architecture to work within MainNavigationPage body
- Minor keypad layout adjustment (77%/23% flex ratio)

+# Flutter Rename Tool
+
+A comprehensive Python script to rename Flutter applications across all platform configurations. This tool handles package names, display names, class names, and bundle identifiers consistently across Android, iOS, and Flutter files.
+
+## Features
+
+- **Automatic detection** of current app configuration across all platforms
+- **Default value support** - Press ENTER to keep current values unchanged
+- **Smart change detection** - Only proceed if changes are actually needed
+- **Comprehensive validation** for package names and app display names
+- **Synchronized updates** across all platform files:
+  - `pubspec.yaml` - Package name and description
+  - `lib/main.dart` - App title and main class name
+  - `android/app/src/main/AndroidManifest.xml` - Android app label
+  - `android/app/build.gradle.kts` - Android namespace and applicationId
+  - `ios/Runner/Info.plist` - iOS display name and bundle name
+- **Automatic Flutter refresh** - Runs `flutter clean` and `flutter pub get` after successful rename
+- **Preview and confirmation** before making changes
+- **Safe execution** with validation and error handling
+
+## Usage
+
+### Interactive Mode
+
+Run the script from your Flutter project root:
+
+```bash
+python tools/flutter_rename.py
+```
+
+The script will:
+1. Detect your current app configuration
+2. Prompt for new package name and app display name
+3. Show a preview of all changes
+4. Ask for confirmation before applying changes
+5. Update all relevant files
+
+### Example Session

+When prompted for input, simply press ENTER to keep the current value:
+```
+New package name (current: archery_scorer): 
+Using current value: archery_scorer
+```
+
+### Smart Change Detection
+The script detects if no actual changes are needed:
+```
+============================================================
+No changes detected - configuration is already up to date.
+============================================================
+```
+
+### Automatic Project Refresh
+After successful renaming, the script automatically runs:
+- `flutter clean` to clear build cache
+- `flutter pub get` to refresh dependencies
+
+No manual steps required - your app is ready to run immediately.
+
+## Post-Rename Steps
+
+If automatic Flutter refresh succeeds:
+1. **Test the application**: `flutter run`
+2. **Verify on all target platforms** (Android, iOS, Web, etc.)
+
+If automatic refresh fails (fallback):
+1. **Clean build cache**: `flutter clean`
+2. **Refresh dependencies**: `flutter pub get`
+3. **Test the application**: `flutter run`
+4. **Verify on all target platforms**
+
+## Safety Features
+
+- **Non-destructive preview** - Shows exactly what will change before applying
+- **File existence checks** - Warns about missing files
+- **Comprehensive validation** - Prevents invalid names
+- **Error handling** - Reports specific issues if updates fail
+- **Backup recommendation** - Always commit your changes to version control first
+
+## Requirements
+
+- Python 3.8 or higher
+- Must be run from Flutter project root directory
+- All target platform files should exist (created by `flutter create`)
+
+## Troubleshooting
+
+**Issue**: "File not found" warnings
+- **Solution**: Ensure you're running from the Flutter project root directory
+
+**Issue**: Some files not updated
+- **Solution**: Check file permissions and ensure files are not read-only
+
+**Issue**: Invalid package name error
+- **Solution**: Follow Dart package naming conventions (lowercase, underscores only)
+
+**Issue**: App doesn't reflect changes after rename
+- **Solution**: Run `flutter clean` and `flutter pub get`, then rebuild
+
+**Issue**: Android app crashes with ClassNotFoundException after rename
+- **Solution**: This indicates the MainActivity wasn't moved to the new package structure - the script now handles this automatically
+
+**Issue**: Tests fail after renaming due to old package imports or class names
+- **Solution**: The script now automatically updates test files with new imports and class references
+
+## Best Practices
+
+### Test Writing for Renamed Apps
+When writing tests, use structural widget checks instead of text-based assertions:
+
+```dart
+// Good - completely localization-safe and robust
+expect(find.byType(MaterialApp), findsOneWidget);
+expect(find.byType(Scaffold), findsAtLeastNWidgets(1));
+expect(find.byIcon(Icons.menu), findsOneWidget);
+expect(find.byKey(const Key('specific-widget')), findsOneWidget);
+
+// Avoid - brittle and breaks with localization  
+expect(find.text('Specific Text'), findsOneWidget);
+expect(find.byTooltip('Open navigation menu'), findsOneWidget);
+```
