feat: 笔记独立窗口改为多标签，AI 多轮会话与 TXT/MD 阅读
笔记独立窗口从「一窗一条」改为单窗口多标签，与阅读器一致： 标签集在主进程侧为权威，notes:tabsChanged 只能收窄不能新增， 否则渲染层可以谎报持有某条笔记来越权读取。存活编辑器上限 3 并 LRU 回收，回收前序列化未保存内容。笔记没有自动保存，关标签与 关窗都做二次确认，取消关闭必须回报主进程复位 closePending， 否则窗口再也关不掉而看门狗仍会销毁未保存内容。 AI 助手支持多轮会话：会话独立落盘，先取历史再写提问， 历史只发文本不重发图像，失败与取消都保留已流出的残片。 新增 TXT/MD 内置阅读（转内存 EPUB 复用 epub 渲染管线）， 补上渲染层遗漏的可阅读格式白名单：主进程本就放行 txt/md， 但渲染层另有两份白名单漏了，表现为卡片上没有「阅读」按钮。 书库卡片封面改用 contain 完整显示，留白由同图模糊层垫底， 修正不同比例封面被裁切程度不一导致的观感不一致；多选复选框 去掉衬底色块，恢复原生外观。 其余：PDF 画质档位与画布尺寸钳制、原子写入、笔记资源托管、 GitHub Pages 站点。
