RoosterJs Editor API (Legacy)

roosterjs-editor-api is a JavaScript/TypeScript package that provided programmatic APIs for interacting with the RoosterJs rich-text editor in its 8.x major version series. This package allowed developers to perform various editor operations such as applying formatting, inserting content, and managing selection directly on an `IEditor` instance. It is now considered deprecated, as the RoosterJs project has transitioned to a new architecture in its 9.x series, primarily utilizing packages prefixed with `roosterjs-content-model-`. The current stable version of this specific package is 8.62.0, with new feature development and ongoing maintenance efforts focused exclusively on the `roosterjs-content-model-api` package. Users are strongly encouraged to migrate to the 9.x content model architecture to benefit from ongoing updates, security fixes, and new features. Its key differentiator was providing a direct API layer for the legacy 8.x editor instances, operating on a DOM-based content model rather than the newer Content Model data structure.
