- Introduced a new TodoListRenderer component to display parsed todo items with status indicators and colors.
- Implemented a parseTodoContent function to extract todo items from TodoWrite JSON content.
- Enhanced LogEntryItem to conditionally render todo items when a TodoWrite entry is detected, improving log entry clarity and usability.
- Updated UI to visually differentiate between todo item statuses, enhancing user experience in task tracking.
