This commit adds a linking exception for the Unity Engine. The GPLv3 creates a legal conflict when linked against proprietary Unity blobs, making the compiled application technically non-distributable. Authorization for this exception was granted by the original author, Michael Voeller, via email on Jan 2, 2026.

This PR adds a Unity Linking Exception to the project's GPLv3 license.
The Legal Deadlock
As a Unity-based project, the current strict GPLv3 creates a legal conflict with Unity's proprietary engine blobs. This prevents the application from being legally packaged or distributed by Linux repositories
Authorization from Original Author
I have obtained explicit written permission from the original creator, Michael Voeller, to add this exception.
Raw email authorization
