Add single-instance tauri plugin

aceArt-GmbH commented 5 months ago

Description

Uses official tauri plugin.

~Currently, if minimized and hidden, it will show but not unminimiz. Also after being shown by a second instance, the tray menu will continue to say "Show Cinny" while it should "Hide Cinny" as it is now shown.~ cc https://github.com/tauri-apps/plugins-workspace/issues/280
