feat(screen-recorder): Add Hyprland focused monitor video source

[Cleboost]

This pull request introduces enhanced support for the Hyprland compositor in the screen-recorder/Main.qml file, allowing for automatic detection of the focused monitor and optimized GPU usage when recording. Additionally, the codebase has been refactored for improved readability and consistency, with semicolons added and minor logic adjustments. The most important changes are grouped below:

Hyprland Support and Focused Monitor Detection

• Added properties (isHyprland, detectedMonitor, usePrimeRun) and a process to detect if Hyprland is running, enabling special handling for Hyprland environments. [1] [2]
• Implemented focused monitor detection using hyprctl and jq, allowing the recorder to target the monitor under the cursor in Hyprland. If an NVIDIA GPU is detected, recording is launched with prime-run for optimal performance. [1] [2]

Refactoring and Code Consistency

• Added semicolons to all statements and improved function formatting for better readability and consistency throughout the file. [1] [2] [3] [4] [5] [6]
• Refactored the recording launch logic to use a new launchRecorderWithSource function, supporting both standard and Hyprland-specific workflows. [1] [2]

Dependency Import

• Added import Quickshell.Io to screen-recorder/Settings.qml, likely to support new or existing IO operations.
