[Feature]: Add support for direct configuration of split tunneling through CLI interface.

[DtDEncryption]

Preflight checks

• I have searched existing issues and this feature has not already been requested.
• This request is for the Windscribe desktop app (not the browser extension, mobile app, or web dashboard).
• I understand that incomplete requests may be closed without further discussion.

Problem or motivation

So far, Windscribe application, whether it's GUI or CLI, does not support controlling split tunneling through CLI directly.

Proposed solution

Expand the CLI interface by adding subcommands or arguments to support configuring split tunneling. This could work like Mullvad VPN's mullvad-exclude, or take the form of a new interface for managing all split tunneling settings through the CLI.

Alternatives considered

For now, I can only manage the settings through GUI. But since such settings is somewhat deep inside, it usually takes some navigation to the split tunneling section.

I saw in the documents Linux-CLI version accept preference reload, which could help manage settings conveniently with scripts, but I love glanceable info displayed by GUI and wouldn't want to trade this for that.

Which platforms should this apply to?

All platforms
