Fair enough, had a look and I agree this does fix a few things.

Description:
Issue #34 reported a frontend initialization failure in ScatterWidget in non Jupyter AnyWidget runtimes because class button initialization could touch circle_brush before it was initialized.
This PR updates ScatterWidget initialization to avoid referencing circle_brush before declaration in both source and bundled frontend files. The behavior stays the same after initialization, but the widget no longer raises a startup ReferenceError in AnyWidget runtimes.
It also adds a focused regression test for the circle_brush init order.
Closes #34.
