issue: Kanban claims drag-and-drop but uses click-based arrows instead
description
The feature list mentions a drag-and-drop Kanban workflow but in the deployed app tasks are moved using arrow buttons instead of actual drag-and-drop.
current behavior
- Tasks can only be moved by clicking left/right arrow icons
- No drag-and-drop interaction between columns
expected behavior
- Tasks should be draggable between columns (backlog, In Progress, Done)
- Smooth mouse and touch-based dragging, especially on desktop
suggested fix
- Replace arrow-based movement with proper drag-and-drop
- Use
@dnd-kit/core and @dnd-kit/sortable
- Accessible and mobile-friendly
- Works well with React and next
- Suitable for Kanban-style layouts
