* feat(engine): 添加编辑器模式标志控制编辑器UI显示 - 在 Rust 引擎中添加 isEditor 标志，控制网格、gizmos、坐标轴指示器的显示 - 运行时模式下自动隐藏所有编辑器专用 UI - 编辑器预览和浏览器运行时通过 setEditorMode(false) 禁用编辑器 UI - 添加 Scene.isEditorMode 延迟组件生命周期回调，直到 begin() 调用 - 修复用户组件注册到 Core ComponentRegistry 以支持序列化 - 修复 Run in Browser 时用户组件加载问题 * fix: 复制引擎模块的类型定义文件到 dist/engine * fix: 修复用户项目 tsconfig paths 类型定义路径 - 从 module.json 读取实际包名而不是使用目录名 - 修复 .d.ts 文件复制逻辑，支持 .mjs 扩展名
