Draggable UI Windows with Screen Constraints

🎯 What is this?

A lightweight, drag-and-drop solution for making your UI windows draggable while keeping them perfectly within screen boundaries. 

✨ Features

• Smooth Dragging: Click and drag any UI element by its handle (title bar, header, etc.)
• Auto Screen Clamping: Windows automatically stay within screen boundaries.
• Bring to Front: Clicked windows automatically come to the front, just like professional desktop applications
• Easy Toggle: Enable/disable screen constraints with a single checkbox
• Zero Dependencies: Works with Unity's built-in UI system (no external packages required)
• Performance Optimized: Lightweight script with minimal overhead

🚀 How to Use

1. Attach the script to your window's drag handle (like a title bar)
2. Set the parent - The script automatically detects the parent transform to move
3. Done! Your window is now draggable and screen-constrained
