fix(pack): add node_modules to watch ignore options

[fireairforce]

Summary

在 linux gun 场景里面使用 devServer 的时候监听 node_modules 里面的文件变更会有比较大的性能损失。

目前 webpack 默认不监听 node_modules 中的依赖文件变更。

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!

此拉取请求旨在通过在文件监听配置中默认忽略 node_modules 目录来解决在 Linux 开发环境中 devServer 监听文件变更时可能出现的性能问题。这一改动确保了文件系统监听器不会处理 node_modules 内部的频繁变动，从而显著提升开发体验和系统效率。

Highlights

• WatchOptions 结构体新增 ignored 字段: 在 crates/pack-api/src/project.rs 中，WatchOptions 结构体新增了一个 ignored 字段，用于指定文件监听时需要忽略的路径，默认值为 node_modules。
• 文件系统创建逻辑更新: Project::disk_fs 方法现在会获取配置中忽略的路径，并在创建 DiskFileSystem 时传递这些路径，以确保文件监听器不会监控这些目录。
• NAPI 和 Schema 层支持 ignored 选项: crates/pack-napi/src/pack_api/project.rs 和 crates/pack-schema/src/lib.rs 中的相关结构体也新增了 ignored 字段，使得该配置可以通过 NAPI 接口和配置 Schema 进行设置和传递。
• next.js 子模块更新: next.js 子模块已更新到最新提交，以集成 pack 模块的这些性能改进。

Code Review

这个 PR 通过添加一个选项来在文件监听时忽略指定路径，从而提高了性能，默认忽略 node_modules。这与 Webpack 的行为类似，是一个很好的改进。代码在 API、N-API 和 schema 层的修改看起来是正确的。我有一个关于移除重复的默认值以提高代码可维护性的建议。
