新增 PDF/EPUB/MOBI/AZW 内置阅读器，PDF 分段读取支持超大文件， 批注、读书与画布笔记、封面生成与本地导入。AI 助手支持三种协议、 图像上下文与安全 Markdown 渲染，上下文范围改为 选中/当前页/全文， 页面与全文无需选中文本即可发送，全文会提示可能超出模型限制。 便携版输出目录固定为 PeopleLib-windows-x64，不再随版本号变化， 避免升级后 data/ 被遗留在旧目录。 Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
