Integrate Quickshell-Overview with Qt6 fixes and automation scripts

## Overview
This commit integrates the corrected Quickshell-Overview feature across all
installation and update workflows. The overview provides an AGS alternative
with live window previews toggled via Super+TAB keybind.

## Changes

### 1. Quickshell Overview QML Files
- Added config/quickshell/overview/ subdirectory with Qt6-compatible QML
- Includes 20+ files covering:
  * OverviewWindow.qml with proper clipping (no OpacityMask, uses QtQuick.Effects)
  * OverviewWidget.qml for window handling
  * Overview.qml main component with Hyprland integration
  * Common utilities and styling
  * Services for Hyprland data and global state management

### 2. copy.sh Updates
- Removes default shell.qml that blocks quickshell named config detection
- Auto-copies config/quickshell/overview to ~/.config/quickshell/overview/
- Updates old 'qs' startup commands to 'qs -c overview'
- Handles both fresh installs and config overwrite scenarios

### 3. upgrade.sh Updates
- Added config/quickshell/ to upgrade directory list
- Excludes shell.qml to preserve overview config detection capability
- Enables seamless upgrades without losing quickshell settings

### 4. IPC Command Fixes
- Corrected OverviewToggle.sh to use proper 'qs ipc -c overview call overview toggle'
- Fixed startup commands from old 'qs' to 'qs -c overview'
- Hyprland-Dots now uses corrected toggle script

## Qt6 Compatibility
- Replaced Qt5Compat.GraphicalEffects with QtQuick.Effects
- Removed OpacityMask in favor of Qt6-compatible clipping technique
- All QML properly imports Qt6 modules

## Release Script
- release.sh automatically uses copy.sh, inheriting all quickshell updates

## Testing
- Verified on target systems (Fedora 43 VM, jak-nixos)
- qs -c overview successfully launches overview config when shell.qml is removed
- IPC toggle commands work correctly within Wayland sessions

## Files Modified
- config/quickshell/overview/* (20 new files)
- copy.sh (enhanced QS handling)
- upgrade.sh (added quickshell to upgrade paths)

+   ```bash
+   git clone https://github.com/Shanu-Kumawat/quickshell-overview ~/.config/quickshell/overview
+   ```
+
+2. **Add keybind** to your Hyprland config (`~/.config/hypr/hyprland.conf`):
+   ```conf
+   bind = Super, TAB, exec, qs ipc -c overview call overview toggle
+   ```
+
+3. **Auto-start** the overview (add to Hyprland config):
+   ```conf
+   exec-once = qs -c overview
+   ```
+
+4. **Reload Hyprland**:
+   ```bash

+
+## ⚙️ Configuration
+
+> **⚠️ Want to change the size, position, or number of workspaces?**  
+> Edit `~/.config/quickshell/overview/common/Config.qml` - it's all there!
+
+### Workspace Grid
+
+Edit `~/.config/quickshell/overview/common/Config.qml`:
+
+```qml
+property QtObject overview: QtObject {
+    property int rows: 2        // Number of workspace rows
+    property int columns: 5     // Number of workspace columns (10 total workspaces)
+    property real scale: 0.16   // Overview scale factor (0.1-0.3, smaller = more compact)
+    property bool enable: true
+}
+```
+
+**Common adjustments:**
+- **Too small?** Increase `scale` (try 0.20 or 0.25)
+- **Too big?** Decrease `scale` (try 0.12 or 0.14)
+- **More workspaces?** Change `rows` and `columns` (e.g., 3 rows × 4 columns = 12 workspaces)
+
+### Position
+
+Edit `~/.config/quickshell/overview/modules/overview/Overview.qml` (line ~111):
+
+```qml
+anchors {
+    horizontalCenter: parent.horizontalCenter
+    top: parent.top
+    topMargin: 100  // Change this value to move up/down
+}
+```
+
+### Theme & Colors
+
+Edit `~/.config/quickshell/overview/common/Appearance.qml` to customize:
+- Colors (m3colors and colors objects)
+- Font families and sizes  
+- Animation curves and durations
+- Border radius values
+
+---
+
+## 📋 Requirements
+
+- **Hyprland** compositor (tested on latest versions)
+- **Quickshell** (Qt6-based shell framework)
+- **Qt 6** with the following modules:
+  - QtQuick
+  - QtQuick.Controls
+  - QtQuick.Layouts
+  - Qt5Compat.GraphicalEffects
+  - Quickshell.Wayland
+  - Quickshell.Hyprland
+
+## 🚫 Removed Features (from original illogical-impulse)

+
+- App search functionality
+- Emoji picker
+- Clipboard history integration
+- Search widget
+- Integration with the full illogical-impulse shell ecosystem

+Extracted from the overview feature in [illogical-impulse](https://github.com/end-4/dots-hyprland) by [end-4](https://github.com/end-4).
+
+Adapted as a standalone component for Hyprland + Quickshell users who want just the overview functionality.
