// DraftDown sample plugin — adds a "Plugins → Make Box" menu item that draws a
// 1×1×1 cube at the origin. Mirrors a DraftDown Ruby extension layout.
//
// In DraftDown Ruby this would look like:
//
//   require 'draftdown.rb'
//   require 'extensions.rb'
//
//   module Example
//     module SampleBox
//       def self.make_box
//         model = DraftDown.active_model
//         model.start_operation("Make Box", true)
//         pts = [
//           Geom::Point3d.new(0,0,0),
//           Geom::Point3d.new(1,0,0),
//           Geom::Point3d.new(1,0,1),
//           Geom::Point3d.new(0,0,1),
//         ]
//         face = model.entities.add_face(pts)
//         face.pushpull(1)
//         model.commit_operation
//       end
//
//       unless file_loaded?(__FILE__)
//         UI.menu("Plugins").add_item("Make Box") { make_box }
//         file_loaded(__FILE__)
//       end
//     end
//   end
//
// The DraftDown JS port below is a near-mechanical translation: snake_case → camelCase,
// `do … end` → `() => { … }`, `Geom::Point3d.new` → `new Geom.Point3d`.
