tree示例算不算违背单向数据流？

Hi. I agree with the issue that in the Tree Example, there are direct mutations of props - specifically, props.model.children.push(...) and props.model.children = []. This violates Vue’s principle of one-way data flow, where props are meant to be treated as immutable.

It's likely that this approach was chosen intentionally to keep the example concise and focused.
However, it might be beneficial to either:

• include a comment in the example clarifying that the prop mutation is used for simplicity and not recommended in production code, or
• update the example to follow Vue’s best practices, using local state or event emission instead.

I can help refactor the example if needed. What do you think?
