/**
 * Provider component that provides Datanova tracking methods to child components.
 * Must be placed at the root of your component tree.
 *
 * @remarks
 * The DatanovaProvider uses React Context to make the Datanova instance available
 * throughout your application. Initialize the Datanova instance outside of your
 * component tree to prevent re-initialization on re-renders.
 *
 * @example
 * Basic usage with SDK key:
 * ```jsx
 * import { createReactDatanova, DatanovaProvider } from '@datanova/react';
 *
 * // Simple initialization with SDK key
 * const datanova = createReactDatanova("your-sdk-key");
 *
 * function App() {
 *   return (
 *     <DatanovaProvider value={datanova}>
 *       <YourApp />
 *     </DatanovaProvider>
 *   );
 * }
 * ```
 *
 * @example
 * Advanced usage with custom services:
 * ```jsx
 * import { createReactDatanova, DatanovaProvider } from '@datanova/react';
 * import { DatanovaEventsService, DatanovaExperimentsService } from '@datanova/browser';
 *
 * // Custom configuration with specific services
 * const datanova = createReactDatanova({
 *   eventsService: new YourEventsService(),
 *   experimentsService: new YourExperimentsService()
 * });
 *
 * function App() {
 *   return (
 *     <DatanovaProvider value={datanova}>
 *       <YourApp />
 *     </DatanovaProvider>
 *   );
 * }
 * ```
 *
 * @example
 * Development usage with ConsoleEventsService:
 * ```jsx
 * import { createReactDatanova, DatanovaProvider } from '@datanova/react';
 * import { ConsoleEventsService } from '@datanova/browser';
 *
 * // Use ConsoleEventsService for development/debugging
 * const datanova = createReactDatanova({

 * });
