fix: 兼容一下部分库的浏览器入口配置

[SANmq]

具体表现为qrcode这种node环境和浏览器环境不同代码的，且在package.json中配置了browser的库。升级项目采用mfsu时遇到打包依赖报错，入口选择node版本的。也希望官方给出更好的方案，遇到问题的库时 qrcode@1.5.3

Walkthrough

此次修改主要是增强了对某些库（如 qrcode）的地址解析兼容性，这些库在其 package.json 文件中配置了 browser 入口点。具体实现是通过在 resolveUtils.ts 文件中的 browserResolver 中添加 aliasFields: ["browser"] 来实现的。

Changes

文件路径	变更摘要
packages/mfsu/src/utils/resolveUtils.ts	在 browserResolver 中添加了 aliasFields: ["browser"] 以支持解析带有 browser 入口点的库

代码改动如春风， 解析兼容更从容。 aliasFields 新添处， 库中路径不迷蒙。

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to full the review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.

感觉不是 resolve 配置的问题，我新创建一个 umi 项目，安装 qrcode ，然后按照官方 readme 里的 demo 使用是正常运行的。

你试试官方给的测试用例，examples/mfsu-independent这个项目，你下个qrcode试试看，我试了一下dev报错

[SANmq]

关于resolveUtils.test.ts里的测试用例我看过了，没有{ "name": "qrcode", "version": "1.5.3", "main": "./lib/index.js", "browser": { "./lib/index.js": "./lib/browser.js", "fs": false } }的例子。即browser是一个对象的例子，至于umi项目为啥没这个问题我没有尝试过，umi项目使用的时候用的是eager策略，这个我不清楚能不能用在我们那个项目上，试了一下配置了eager运行会报错。
