/**
 * Foundation component for all widgets that manages state initialization, synchronization with the widget store, and data transformation pipeline execution.
 *
 * @remarks
 * The WidgetLoader is stateless -- it manages data flow but does not render any UI. Always wrap it with WidgetWrapper for consistent widget appearance.
 *
 * @example
 * ```tsx
 * <WidgetLoader
 *   id="sales-chart"
 *   type="bar"
 *   data={data}
 *   isLoading={false}
 *   isFetching={false}
 *   config={barConfig({ data })}
 * >
 *   <WidgetWrapper id="sales-chart" title="Sales">
 *     <Echart id="sales-chart" />
 *   </WidgetWrapper>
 * </WidgetLoader>
 * ```
