Drop the Jump-to-Reference Navigation section from README; bump to 1.2.9

bullets. Docs only.

-Open a model and its **Model References** and **External Data** appear as links. Click one and the referenced file — a submodel (`.slx`), a linked data dictionary (`.sldd`), or a MAT-file (`.mat`) — opens right away, resolved from your workspace. It's how you'd expect cross-file navigation to work in an editor: follow the dependency chain without hunting through folders.
