feat: implement comprehensive directory creation for Android 10+ 

- Add 4-strategy directory creation system for Android 10+ compatibility
- Strategy 1: Recursive file creation with temporary files
- Strategy 2: Parent-by-parent directory creation for nested paths
- Strategy 3: Simple file test creation in target directory
- Strategy 4: App-specific external directory creation
- Enhanced testing and user guidance for directory creation capabilities
- Comprehensive logging for debugging directory creation issues
- Guaranteed file saves with graceful fallback to app data directory
