Fix/UI sync update

[ash1shkumar]

📌 Overview

This update delivers a redesigned Kanban system focused on deterministic state updates, improved interaction reliability, and stronger separation between UI rendering and state transitions. It enhances consistency across drag operations and real-time updates.

---

✨ Highlights

⚙️ Deterministic Task Flow

• Introduced predictable task ordering model
• Stabilized status transitions across columns
• Ensured consistent position recalculation after updates

🧠 Architecture Improvements

• Clean separation of board logic and column rendering
• Unified type model for Task, Column, and TaskStatus
• Reduced coupling between UI and data mutation layers

🎯 Interaction Stability

• Fixed edge cases during fast drag operations
• Prevented duplicate state propagation from socket events
• Improved responsiveness during rapid UI updates

🔄 Real-Time Sync Enhancements

• Smarter socket event handling with de-duplication
• Safer reconciliation of incoming updates
• Reduced UI flicker during concurrent updates

---

📊 UI & UX Improvements

• Smoother drag-and-drop experience
• Clear empty-state handling in columns
• Better visual feedback during drop interactions
• More stable re-render behavior

---

🧪 Validation Performed

• Drag across multiple columns under rapid interaction
• Concurrent updates via socket simulation
• Task reorder validation within same column
• Empty state rendering checks
• TypeScript strict mode verification

---

⚠️ Compatibility

• Requires @dnd-kit/core and @dnd-kit/sortable
• Backend must support status and position fields

---

Fixes #422

🏷 Labels

level3, NSoC'26

---

📦 Impact

This release significantly improves Kanban stability under high interaction load and lays the foundation for future real-time collaboration features.
