name: 粘贴摘录解析引擎
description: 后台引擎：拦截并解析粘贴板中的特殊格式（BookxNote、Zotero、Eagle、Bookmaster及自定义ymjr等）为带链接的 Excalidraw 元素。
author: ymjr
version: 1.0.0
license: MIT
usage: 后台常驻。当您在画板中按下 Ctrl+V 粘贴时，自动探测文本剪贴板中是否包含支持的第三方软件协议链接。如果命中，会自动转换为对应的图片、引用块或代码块元素。
features:
  - 拦截 `onPaste` 钩子，支持 BookxNote Pro, Zotero PDF, Bookmaster, Booknote, Eagle 格式。
  - 支持私有的 `ymjr:` JSON 协议，实现富文本与代码高亮等高级粘贴机制。
  - 智能清洗由于跨软件复制带来的无效 HTML 富文本标签。
dependencies:
  - 独立运行。如果是代码高亮协议，需配合 [CodeHighlight] 模块使用。
