    Playwright 测试执行器（同步版本）

    负责执行测试用例中的步骤，支持多种浏览器操作和断言验证。
    每个步骤自动截图，支持实时回调通知。

    使用同步 Playwright API 以避免 Windows 上 asyncio 子进程的限制。

    功能：
    - 页面导航 (navigate)
    - 元素点击 (click)
    - 输入框填充 (fill)
    - 下拉框选择 (select)
    - 鼠标悬停 (hover)
    - 元素等待 (wait)
    - 断言验证 (assert)
    - 滚动操作 (scroll)
    - 按键操作 (press)
    - 截图 (screenshot)
    - 复选框操作 (check/uncheck)
    - 自动登录 (auto_login) - 新增

    Example:
        >>> executor = PlaywrightExecutor()
        >>> executor.start()
        >>> result = executor.execute_case(case, callback=on_step_complete)
