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
