[Bug]: Linux window controls ignore the system-configured button layout

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. On GNOME, configure a custom window button layout, for example only a close button or controls on the left.
2. Open T3 Code Desktop.
3. Compare T3 Code's window controls with other system windows.

Expected behavior

T3 Code should respect the system-configured window button layout and placement.

For example, if GNOME is configured to show only the close button, T3 Code should do the same.

Actual behavior

T3 Code shows Electron's default Window Controls Overlay layout instead of the layout configured by the desktop environment.

This makes the title bar inconsistent with the rest of the desktop.

T3 Code already uses titleBarStyle: "hidden" with titleBarOverlay on Linux, but it currently uses Electron 41.5.0.

Electron 43 added support for system-configured button layouts in WCO on Linux:

Updating Electron should allow T3 Code to inherit the user's Linux window control layout without replacing the existing custom title bar.

Workaround

Start in apps/desktop by locating the Electron version and the existing titleBarStyle: "hidden" and titleBarOverlay configuration. Run the desktop app on GNOME with different window button layouts and verify the Electron upgrade preserves the custom title bar while matching the system layout.
