/**
 * RadioItemInput Component
 *
 * A composable radio input component that wraps the HTML `<input type="radio">` element.
 * Automatically handles selection state based on RadioGroup context.
 *
 * @public
 *
 * @example
 * ```tsx
 * <RadioGroup name="choice" value={value} onValueChange={setValue}>
 *   <RadioItem value="option1">
 *     <RadioItemInput />
 *     <RadioItemLabel>Option 1</RadioItemLabel>
 *   </RadioItem>
 * </RadioGroup>
 * ```
 *
 * @remarks
 * - Wraps the HTML `<input type="radio">` element by default.
 * - Supports `asChild` prop to merge props with a custom child element.
 * - Automatically applies selection state styling based on context.
 * - Accessible: includes ARIA attributes and keyboard navigation.
