bundle core into lib instead of separate npm package

Remove @react-avatar-editor/core from dependencies and from Vite's
external list so the core code is bundled directly into the
react-avatar-editor dist output. Core remains a separate workspace
package for development but consumers only install react-avatar-editor.
