CKEditor 5 Custom Online Build

This package (`ckeditor5-custom-build`) is a foundational repository generated by the CKEditor 5 Online Builder tool, providing a customizable starting point for a rich-text editor. It is not a directly consumable NPM library but rather the source code and build configuration for a tailored CKEditor 5 instance. As a custom build, its version (0.0.6) reflects its initial state as a template, with no regular release cadence for this specific package. Users are expected to modify, build, and integrate the output into their applications. Key differentiators include the ability to hand-pick features and plugins from the CKEditor 5 ecosystem and self-host the resulting editor, offering complete control over the bundle size and included functionalities, contrasting with pre-built distributions like `@ckeditor/ckeditor5-build-classic`. It's primarily intended for web applications that need a highly specific rich-text editing experience, allowing for granular control over toolbar items, plugin configurations, and overall editor behavior.
