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!

This pull request addresses a parsing issue by adding support for the ~ prefix in Less and Sass import paths. This enhancement ensures that module imports, particularly those referencing packages within node_modules, are correctly resolved. A new snapshot test case has been added to validate this functionality for Less, demonstrating the successful compilation of a stylesheet importing antd/reset.css using the ~ prefix. Additionally, the next.js subproject has been updated.

Highlights

• Less/Sass ~ Prefix Support: Implements support for parsing the ~ prefix in Less and Sass import statements, which is commonly used for resolving modules from node_modules.
• New Snapshot Test Case: Introduces a new snapshot test specifically for Less, demonstrating the correct resolution of an @import '~antd/reset.css'; statement.
• Subproject Update: Updates the next.js subproject to a newer commit (ee0e4f6384c4a22b366d2faded519c4b62750eff).

Code Review

这个 PR 增加了一个快照测试，用于验证在 less 导入中对 ~ 前缀的支持。测试用例结构良好。然而，PR 标题同时提到了 less 和 sass，但目前只添加了 less 的测试。为了确保该功能在 sass 中也能正常工作并防止未来的回归，强烈建议为 sass 也补充相应的快照测试。此外，在测试用的 CSS 文件中发现一个小问题，已在具体评论中指出。
