Summary of Changes

Hello @fireairforce, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在解决 Turbopack 打包器在处理异步 chunk 时可能出现的模块重复问题。通过调整模块的打包和加载机制，确保异步加载的模块能够被正确地去重和引用，从而提升打包效率和输出质量。此次更改主要体现在对现有快照测试输出的更新，以验证修复的有效性。

Highlights

• 异步 Chunk 重复模块修复: 修复了 Turbopack 打包器在处理异步 chunk 时可能包含重复模块的问题，确保打包输出的唯一性。
• 快照测试更新: 更新了多个快照测试的输出文件，以反映修复后的正确打包结果和模块结构变化。
• 模块加载逻辑优化: 优化了异步模块的加载和引用逻辑，以消除打包输出中的冗余。
• Next.js 子项目更新: 更新了 next.js 子项目的引用版本，同步了上游的最新更改。

Code Review

你好！这个 PR 旨在修复异步块中包含重复块的问题。从变更来看，主要是更新了大量的快照测试，这反映了打包器输出结果的变化。我注意到在多个测试用例中，生成包内的模块顺序发生了改变，这通常是打包逻辑变更后的正常现象。

我仔细检查了这些快照，发现了一个关于 stats.json 文件生成的问题，具体请看我的评论。除此之外，这些快照更新看起来与 PR 的目标是一致的。
