Summary

This PR removes the deprecated WarnCaseSensitiveModulesPlugin API and all related documentation. The plugin was renamed to CaseSensitivePlugin in v1.7.0, and WarnCaseSensitiveModulesPlugin has been deprecated since then. This change completes the deprecation cycle by removing the old API name entirely.

The following changes are made:

  • Removed WarnCaseSensitiveModulesPlugin export from packages/rspack/src/exports.ts
  • Removed WarnCaseSensitiveModulesPlugin from API documentation (core.api.md)
  • Updated test cases to use CaseSensitivePlugin instead
  • Removed deprecation notices from plugin documentation
  • Removed WarnCaseSensitiveModulesPlugin from documentation coverage exclusion list

Checklist

  • Tests updated (or not required).
  • Documentation updated (or not required).
