Patch Changes

• Override repr to avoid expensive trait serialization #906 (#906)

  Previously, AnyWidget inherited ipywidgets.Widget.__repr__ which serialized all trait values. This is costly because the repr might not even be shown to users, yet it forces a full serialization of potentially large data. AnyWidget now overrides __repr__ to use object.__repr__(self), which produces a simple <module.ClassName object at 0x...> format.

  To restore the previous behavior showing all trait values, users can define:

  class MyWidget(anywidget.AnyWidget):
      def __repr__(self):
          return traitlets.HasTraits.__repr__(self)
