/**
 * Converts a ReadableStream to an AsyncIterableIterator.
 *
 * This function preferentially uses the native async iteration support
 * and falls back to manual reader-based iteration for environments that
 * don't support it (primarily Safari as of 2025).
 *
 * @template T - The type of values in the stream
 * @param stream - The ReadableStream to convert
 * @returns An AsyncIterableIterator that yields values from the stream
 *
 * @example
 * ```ts
 * const stream = new ReadableStream({
 *   start(controller) {
 *     controller.enqueue('chunk1');
 *     controller.enqueue('chunk2');
 *     controller.close();
 *   }
 * });
 *
 * for await (const chunk of convertStreamToAsyncIterableIterator(stream)) {
 *   console.log(chunk);
 * }
 * ```
