fix(hotkeys): 快捷键系统性修复——1.Ctrl+N onNewDoc 原为空函数, 实现新建文档全流程(dialog+fileCreate+openDoc); 2.Ctrl+backslash clearFormat 原无处理器(actions 缺失), 加 onClearFormat 调用 editor.chain().clearNodes().unsetAllMarks(); 3.use-hotkeys 重写: 移除 hotkeys-js 依赖, 全部绑定统一用捕获阶段 keydown 拦截(先于 Electron 菜单), 加 e.code 符号键映射修复 Shift+符号键匹配; 4.编辑器作用域键在输入框聚焦时仍放行 find(Ctrl+F); keymap-all E2E 8 项覆盖全部 12 默认快捷键
