⚠️ Breaking changes ⚠️

🔄 Core Changes:

• author (type User) is replaced with authorId (type String) for simpler user management
• All DateTime properties now use milliseconds instead of microseconds for JSON serialization

🎨 Theme Simplification: Theme has been streamlined to 3 key parameters:

1. colors - Uses Material 3 semantic names (e.g. primary, onPrimary, secondary) making it easy to apply color schemes
2. typography - Follows Flutter's TextTheme semantic naming conventions
3. shape - Controls border radius of all messages (rounded vs square messages)

✨ Enhanced Customization:

• Individual widget customization available through the builders parameter
• Example: loadMoreBuilder: (context) => LoadMore(color: Colors.red) overrides theme colors
• Full widget customization possible by returning custom widgets from builders
