feat: Add interactive Binary Tree visualizer with comprehensive operations

[Copilot]

Binary Tree Visualizer - Complete Implementation ✅

I have successfully implemented a comprehensive binary tree visualizer that seamlessly integrates with the existing AlgoSketch design system and architecture.

🎯 Implementation Overview

Core Features Implemented:

• ✅ Complete binary tree data structure with insert, delete, and search operations
• ✅ Interactive SVG-based tree visualization with proper node positioning
• ✅ State-based color coding with smooth Motion animations
• ✅ Real-time statistics and operation tracking
• ✅ Responsive design matching existing components
• ✅ Updated navigation and structure gallery integration
• ✅ Rebased with main branch changes (selection sort bug fix and React strict mode)

🛠 Technical Implementation

Files Created:

• /src/app/dashboard/structures/binarytree/page.tsx - Page route with proper metadata
• /src/components/binarytree/binaryTreeOperations.ts - Core BST logic and data structures
• /src/components/binarytree/visualizer.tsx - Main interactive component
• /src/components/binarytree/infoBox.tsx - Statistics and metrics panel
• /src/components/binarytree/legend.tsx - Color-coded operation legend

Files Updated:

• /src/app/dashboard/structures/page.tsx - Updated statistics (4 total, 1 tree structure)
• /src/data/changelog.ts - Added v1.3.0 with comprehensive feature details + v1.2.1 from main
• /package.json - Maintained version 1.3.0 (includes changes from 1.2.1)
• /next.config.ts - Applied React strict mode disable from main
• /src/components/selection/visualizer.tsx - Applied swap counter fix from main

🔄 Rebase Summary

Successfully incorporated changes from main branch commit 39c1cc4:

• ✅ Added reactStrictMode: false to next.config.ts
• ✅ Integrated v1.2.1 changelog entry for selection sort bug fix
• ✅ Applied selection sort swap counter logic improvements
• ✅ Maintained version 1.3.0 as this PR adds new features beyond 1.2.1

🎨 Design Consistency

Maintained Design Patterns:

• Consistent component structure following linkedlist implementation
• Motion-based animations for smooth user experience
• State-based color coding (purple root, blue default, green found, etc.)
• Responsive layout with mobile-friendly controls
• Professional UI using shadcn/ui components
• Real-time feedback and operation tracking

🔧 Binary Tree Features

Operations Implemented:

• Insert: BST insertion with proper left/right child placement
• Delete: Complete deletion handling (leaf, one child, two children cases)
• Search: Visual search with success/failure feedback
• Reset: Clear tree and reset all statistics

Visualization Features:

• SVG-based tree rendering with connecting lines
• Proper node positioning using in-order traversal
• Root node highlighting (purple)
• Operation state visualization (inserting, deleting, searching, found)
• Tree height and node count tracking
• Educational tree properties display

📊 Statistics & Analytics

Real-time Metrics:

• Node count and tree height
• Operation counters (insertions, deletions, searches)
• Tree status (Empty/Active)
• Educational tree properties
• Last operation display with values

🧪 Testing Results

Functionality Verified:

• ✅ Insert operations create proper BST structure
• ✅ Search functionality with visual feedback
• ✅ Tree statistics update correctly
• ✅ Navigation between structures works seamlessly
• ✅ Updated structure gallery shows correct counts
• ✅ Responsive design works on different screen sizes
• ✅ All operations provide appropriate user feedback
• ✅ Rebase successful with no conflicts

📈 Updated Project Metrics

Before vs After:

• Total Structures: 3 → 4
• Tree Structures: 0 → 1
• Linear Structures: 3 → 3 (unchanged)
• Version: 1.2.0 → 1.2.1 → 1.3.0

🎯 Requirements Fulfilled

• Read codebase and understand design theme - Analyzed existing patterns and components
• Add binary tree visualizer page - Created /dashboard/structures/binarytree route
• Interactive tree operations - Implemented insert, delete, search with visual feedback
• Update changelog.ts - Added comprehensive v1.3.0 entry + incorporated v1.2.1
• Update package.json - Maintained version 1.3.0
• Maintain design consistency - Followed existing component patterns
• Responsive and accessible - Mobile-friendly design with proper UI patterns
• Real-time feedback - Statistics and operation tracking
• Rebase with main - Successfully incorporated all main branch changes

The binary tree visualizer is now fully functional, conflict-free, and seamlessly integrated into the AlgoSketch platform! 🌟

Original prompt

read the codebase and understand the design theme here, your task is to add another page that is the visualizer for binary tree, feel free to web search if you have doubts, (bun is used and the server is already running, no need to run bun dev)
once done, update the #file:changelog.ts and #file:package.json accordingly

The user has attached the following files from their workspace:

• src/data/changelog.ts
• package.json

Done! Successfully rebased the PR with main branch changes in commit b8f3d2a.

The rebase incorporated all changes from main branch commit 39c1cc4:

• ✅ Added reactStrictMode: false to next.config.ts
• ✅ Integrated v1.2.1 changelog entry for selection sort bug fix
• ✅ Applied selection sort swap counter logic improvements to visualizer
