fix(react,vue): forward multiCursor through Editor components

[karen1522158173]

Summary / 摘要

Forward multiCursor from the React/Vue <Editor /> wrapper components to the core editor config.

Motivation / 背景与动机

• Issue: N/A
• Roadmap: N/A
• OpenSpec change: N/A

The core editor already supports the multiCursor option, and both React/Vue useEditor hooks can pass editor config through to createEditor.

However, the React and Vue <Editor /> wrapper components did not forward the multiCursor prop to the core editor config. In React, the prop could also be forwarded to the DOM wrapper instead of being consumed by the editor component.

This PR fixes the wrapper behavior so framework users can enable or disable multi-cursor support through the existing multiCursor prop.

Changes / 变更内容

• packages/react:

  • Forward multiCursor from the React <Editor /> component to useEditor.
  • Add regression tests for both multiCursor={true} and multiCursor={false}.

• packages/vue:

  • Add multiCursor to Vue editor prop keys and runtime props.
  • Ensure multiCursor is included in the config passed to useEditor.
  • Add regression tests for both multiCursor: true and multiCursor: false.

• packages/core:

  • No changes. Core already supports multiCursor.
