[Feature]: Add a script generation feature to playground mode

What problem does this feature solve?

Recorder mode can automatically generate playwright/yaml scripts after recording operations. Could playground mode add a similar feature — after executing all steps via natural language, provide a button that lets the user choose whether to generate a script, and allow them to choose the script style (autonomous planning or workflow)?

Title: [Feature]: playground模式增加生成脚本功能

What problem does this feature solve?

recorder模式可以录制操作后自动生成playwright/yaml脚本，那么playground模式能不能新加个功能，根据自然语言执行完所有步骤后，加个按钮让用户选择要不要生成脚本，并且可以选择脚本风格是自主规划或者工作流。

Start by locating the playground mode implementation and the recorder flow that generates Playwright/YAML scripts. Compare how script-style selection works there, then define the playground button, autonomous-planning and workflow choices, and verify that scripts can be generated after all natural-language steps finish.
