Ember CLI Preprocessor Registry

Ember CLI Preprocessor Registry (npm: `ember-cli-preprocess-registry`) is an internal utility package within the Ember CLI ecosystem, providing a centralized registry for managing various preprocessors for `css`, `template`, and `js` assets. It is currently at version 5.0.1 and primarily maintained as needed for Ember CLI development, without a strict independent release cadence. Its key differentiator is its deep integration into Ember CLI's build pipeline, offering a standard way for addons to register and interact with asset transformations via hooks like `setupPreprocessorRegistry`. This package is not typically consumed directly by end-user applications but is a core component for Ember CLI addons wishing to extend asset compilation.
