Summary of Changes

Hello @chenjiahan, 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 streamlines the Module Federation plugin by removing a previously necessary workaround for chunk splitting conflicts. An upstream fix has rendered the split-by-experience chunk splitting rule compatible with shared modules, allowing for the removal of the custom strategy override and associated documentation. This simplifies the plugin's logic and improves its maintainability.

Highlights

  • Obsolete Chunk Split Rule Removal: The logic that previously forced the split-by-experience chunk splitting strategy to custom within the Module Federation plugin has been removed.
  • Upstream Fix Integration: This change is a direct result of an upstream issue being resolved, which made the previous workaround for chunk splitting conflicts unnecessary.
  • Documentation Cleanup: Corresponding documentation in both English and Chinese has been updated to remove references to the now-obsolete chunk splitting workaround.

With the removal of this workaround, the behavior of chunk splitting with module federation changes. The test snapshots in packages/core/tests/moduleFederation.test.ts will likely need to be updated to reflect this. Please run the tests and update the snapshots accordingly.
