EasyFill v1.3 发布：支持SPA机制、优化 Shadow DOM 遍历逻辑

const processedShadowRoots = new WeakSet<ShadowRoot>();

function traverseShadowDOM(root: Document | ShadowRoot | Element) {
  // 如果 ShadowRoot 已经处理过，跳过
  if (root instanceof ShadowRoot && processedShadowRoots.has(root)) {
    return;
  }

  // 标记已处理的 ShadowRoot
  if (root instanceof ShadowRoot) {
    processedShadowRoots.add(root);
  }
}

function setupAdvancedPageChangeDetection() {
  // 监听浏览器前进后退
  window.addEventListener('popstate', () => {
    logger.info('检测到 popstate 事件');
    handlePageChange();
  });

  // 监听 PJAX、AJAX
  const originalPushState = history.pushState;
  const originalReplaceState = history.replaceState;

  history.pushState = function(...args) {
    originalPushState.apply(history, args);
    logger.info('检测到 pushState 事件');
    setTimeout(() => handlePageChange(), 100);
  };

  // 监听 hashchange 事件
  window.addEventListener('hashchange', () => {
    logger.info('检测到 hashchange 事件');
    handlePageChange();
  });

  // DOM 变化检测
  const observer = new MutationObserver((mutations) => {

      let significantChanges = 0;

      mutations.forEach((mutation) => {
        if (mutation.type === 'childList') {
          // 检查大量节点变化
          if (mutation.addedNodes.length > 5 || mutation.removedNodes.length > 5) {
            significantChanges++;
          }

            }
