feat: Application prototype (#14)
Creates a prototype user interface for dyna3 in the `app-proto` folder. The interface is dynamically constructed using [Sycamore](https://sycamore.dev). The prototype includes: * An application state model (the `AppState` type) * A constraint problem model (the `Assembly` type), used in the application state * Two views * A 3D rendering of the assembly (the `Display` component) * A list of elements and constraints (the `Outline` component) The following features confirm that the views can reflect and send input to the model: * You can select elements by clicking and shift-clicking them in the outline. The selected elements are highlighted in the display. * You can add elements using a button above the outline. The new elements appear in the display.
