Implement Task Panel with Dark Theme

[birdup000]

Here's a detailed scope for a junior developer to build a task panel with a dark theme in the ADHD-TaskManagementPanel project, following existing patterns and providing clear guidance:

1. Project Setup and Familiarization: Clone the repository, install dependencies (npm install or yarn install), and start the development server (npm run dev or yarn dev). Explore the existing codebase, focusing on the app/ directory for pages and layouts.
2. Create Task Panel Component: Create a new component named TaskPanel.tsx inside a new directory components/TaskPanel.
3. Define Task Data Structure: Define a Task interface in types/task.ts (or a similar location):

   interface Task {
     id: string;
     title: string;
     description?: string;
     dueDate?: Date;
     priority?: 'high' | 'medium' | 'low';
     status: 'open' | 'in progress' | 'completed';
   }

4. Implement Task List Display: In TaskPanel.tsx, display a list of tasks using the Task interface. Start with hardcoded data for testing, styled with Tailwind CSS.
5. Implement Add Task Functionality: Add a form to create new tasks, managing input values with useState. On submission, create a new Task object and add it to the task list.
6. Implement Edit Task Functionality: Allow users to edit tasks by displaying a form populated with existing task data. Update the task in the list upon saving changes.
7. Implement Delete Task Functionality: Add a delete button/icon to each task, removing the task from the list upon clicking.
8. Implement Drag and Drop Functionality: Use react-beautiful-dnd to enable drag and drop functionality for moving tasks between status columns ("Open," "In Progress," "Completed").
9. Dark Theme Implementation: Implement a dark theme using Tailwind CSS's dark mode feature and a toggle switch. Store the theme preference in local storage (consider using next-themes).
10. Styling and UI Polish: Refine the UI with attention to spacing, typography, and color choices. Ensure responsiveness and consistency with the existing UI, utilizing the Geist font family.
11. Integrate Task Panel into Main Layout: Include the TaskPanel component in app/page.tsx or relevant layout files.
12. Data Persistence: Use localStorage to save and retrieve the task list, persisting data across sessions.
13. Error Handling and Validation: Validate form inputs and display error messages to improve the user experience.
14. Code Documentation: Document components and functions using JSDoc-style comments.
15. Testing: Write unit and integration tests using Jest or Mocha to test core functionalities.
16. Code Review and Refactoring: Have a senior developer review the code for quality and adherence to standards.
17. Accessibility Considerations: Ensure the task panel is accessible to users with disabilities. Use semantic HTML, provide alternative text for images, and ensure sufficient color contrast. Test with screen readers.
18. Optimize Performance: Implement code splitting, lazy loading, and memoization to improve performance.
19. Commit Changes: Commit changes with descriptive messages, following a consistent format.
20. Create Pull Request: Create a pull request with a detailed description of the changes.
