Tray icon support on Wayland (Hyprland)

Feature Request: Tray icon support on Wayland

Current behavior

The tray icon feature works on X11/Windows (implemented in #1352), but on Wayland compositors (e.g. Hyprland) the tray icon does not appear and minimizing/closing to tray is not possible.

Expected behavior

• Minimize to tray icon when clicking the minimize button (optional, via settings)
• Close to tray icon when clicking the close button (optional, via settings)
• Tray icon should be visible and functional on Wayland compositors that support the StatusNotifierItem (SNI) protocol (KDE Plasma, Hyprland + tray applet, etc.)

Technical context

Wayland does not use the legacy X11 _NET_SYSTEM_TRAY protocol. Instead, it relies on the StatusNotifierItem (SNI) / AppIndicator specification. Electron supports this via:

• Tray API with --enable-features=UseOzonePlatform --ozone-platform=wayland flags
• Or ensuring the app is launched with proper Wayland/XWayland environment

Most Wayland compositors with a tray (Waybar, swaybar, etc.) support SNI natively.

Environment

• OS: Arch Linux
• Compositor: Hyprland (Wayland)
• Nuclear version: latest
• Installation method: AUR

Why this is different from existing closed issues

Issues #932, #1149 were generic "minimize to tray" requests. This specifically targets the Wayland protocol incompatibility with the existing tray implementation, which is a distinct technical problem.
