- **Package Transformation**\
  Automated copying and modification of `package.json`, allowing selective removal of fields to produce a clean, production-ready manifest.

- **Dynamic Exports Generation**\
  Automatically generates `exports` maps based on build outputs, ensuring correct module resolution for ESM and CommonJS environments.

- **Dependency Optimization**\
  Integrates with the build pipeline to control dependency handling and reduce unnecessary bundle inclusion.

- **Build-Time Integration**\
  Seamlessly hooks into the Rolldown lifecycle to perform transformations efficiently during the build process.
