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)
