 * Navigation adapter for extension platform

 * - Querying active tab information
 * - Sending navigation commands to active tab
 * - Extracting routes from page context

 * Note: This adapter maintains cached state since some methods must be synchronous
 * while Chrome APIs are async.
 *
 * @example
 * ```typescript
 * const adapter = new ExtensionNavigationAdapter();
 * await adapter.navigate('/products');
 * const currentPath = adapter.getCurrentPath();
 * ```
