[BUG] Lit MultipleChoice component has broken HTML binding and state reflection

[shantoislamdev]

Description

The MultipleChoice component in the Lit renderer (renderers/lit) contains two significant bugs that prevent it from functioning correctly and rendering valid HTML.

Issues

1. Invalid HTML Attribute Binding

Location: renderers/lit/src/0.8/ui/multiple-choice.ts
The code incorrectly binds the option value directly as an attribute name:

// Current Code
return html`<option ${option.value}>${label}</option>`;

Result: Renders as <option valueContent>Label</option>, which is invalid HTML for a value binding.

2. Missing State Reflection

The component fails to bind the selected value to the <select> element. The UI always displays the default (first) option even if the model has a different selection.

Expected Behavior

1. Options should render as <option value="valueContent">Label</option>.
2. The dropdown should show the option corresponding to this.selections as selected.
