Add auto start minimized option for the client

[minimalguru-dev]

It would be useful to have an option that allows the client to start minimized when launched, particularly when it is configured to run automatically at system startup.

Add a setting such as “Start minimized” that, when enabled:

Launches the client without opening the main window.
Keeps the client running in the background or system tray.
Allows users to open the main window normally when needed.

For users who configure the client to launch automatically at startup, opening the main window every time can be unnecessary and disruptive. A start-minimized option would provide a cleaner startup experience while keeping the client readily available.

Thanks for considering this feature.
