Windows key and Ctrl+Windows are not recognized as shortcuts

Observed behaviour

On Windows, global shortcuts that use the Windows key are not recognized by Fluxer. In particular, Ctrl+Windows does not work as a shortcut, and assigning the Windows key by itself also does not work. This prevents using these bindings to mute/unmute or use push-to-talk while speaking in another app (for example, Wispr Flow). Other shortcut combinations work. Expected: the configured Windows-key shortcut should trigger the selected voice action globally, including while Fluxer is unfocused, subject to Windows-reserved shortcuts.

Reproduction steps

Open Fluxer Desktop on Windows and join a voice channel.
In keybind settings, assign the desired voice action (for example, Toggle Mute or Push to Talk) to Ctrl+Windows.
Focus another app and press Ctrl+Windows; observe that Fluxer does not trigger the action.
Repeat with the Windows key by itself as the configured shortcut; it also does not trigger the action.
