Release v1.5.1

VRChat Immersive Scaler v1.5.1

Import Hotfix

• Removes an accidentally packaged zero-byte icon file that caused Unity to log File could not be read on import.
• Defers viewport gizmo icon toggling until Unity has created the annotation, avoiding the import-time Annotation not found! warning.
• Keeps automatic import handling quiet; manual debug menu actions still report their result.
