menubar setting is active:

New Features:

## Summary by CodeRabbit

* **New Features**
* Configurable menubar/tray behaviors: open on left-click, minimize to
tray, close to tray (exit to tray), and start minimized.

* **UI**
* Appearance settings add a Menubar → Window Behavior group with four
toggles; group shows only when menubar/tray is enabled (hidden on
macOS).

* **Settings**
* Tray settings persisted and exposed via the settings API with getters
and setters for each option.

* **Localization**
* Added translation keys and English strings for the new controls and
descriptions.
