## ✨ New Utility Added: `installWindowHiddenScript`

This release introduces the `installWindowHiddenScript` function — a lightweight utility that dynamically applies CSS classes to an element based on window/tab visibility and focus state.

### 📌 Highlights

* 🧠 Automatically detects when the window is visible or hidden
* 🚀 Triggers the initial state immediately on install
* 🔧 Returns a cleanup function to remove all listeners

Perfect for status indicators, visual feedback, and more!
