Fresh install into an empty project failing on Unity 6.3 LTS with Newtonsoft import errors

[hlibr]

Steps to reproduce:

1. Create an empty project in Unity 6.3 LTS
2. Import LLMUnity from My Assets
3. Watch the errors in the console:

Assets/LLMUnity/Runtime/LlamaLib/LLM.cs(6,7): error CS0246: The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)

Platform: MacOS 26
LLMUnity version: 3.0.3

A workaround is to manually install com.unity.nuget.newtonsoft-json via Package Manager -> Install package by name

Hi! I'll test it out, it worked for me in the past in a clean project.
