refactor(dev): 🔥 reduce ensure2 chunk map size

[stormslowly]

the former installable_descendants_chunk returns almost all the chunk in this build.
sync_dependencies_chunk is the best choice and aligning with production behaviors

Summary by CodeRabbit

Walkthrough

该变更主要涉及对 crates/mako/src/plugins/central_ensure.rs 中 CentralChunkEnsure 插件的 module_ensure_map 函数的修改。主要变化是将方法 installable_descendants_chunk 重命名为 sync_dependencies_chunk，用于获取动态导入模块的依赖项。此外，代码现在在 sync_dependencies_chunk 的结果上调用 once(&chunk.id)，确保当前块 ID 被包含在依赖列表中。函数的整体结构保持不变，错误处理和控制流也未显著改变。

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.
  • @coderabbitai help me debug CodeRabbit configuration file.

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.

36-38: 优化: 减少 ensure2 chunk map 大小的改动

这个改动通过以下方式优化了依赖收集:

1. 使用 sync_dependencies_chunk 替代了返回几乎所有 chunks 的 installable_descendants_chunk
2. 通过 chain(once(&chunk.id)) 确保当前 chunk 被包含在依赖列表中

这样的改动更符合生产环境的行为，同时也能有效减少 chunk map 的大小。

建议添加单元测试来验证:

1. chunk map 大小确实减少
2. 动态导入的模块仍能正确加载
