Setting `bind:value` or `bind:valueAsNumber` for a number input seems to
restrict what you can type in it. We work around this by switching to
text inputs for now. We should probably switch back to number inputs if
we can, though, because they let us take advantage of the browser's
parsing and validation.
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.
