Feature: Add System Tray Support

[YoganshSharma]

The system tray should provide quick access to common actions. Ensure that the tray works even when the main window is closed/minimized.

Tasks/Requirements

• Design tray icon
• (maybe) Tray icon should indicate current status (e.g., active, paused, error) via color or overlay if possible.
• Implement menu actions on right click (Show/Hide, Pause/Resume, Check for Updates, Quit)
• Test on Windows, Linux, and macOS
