refactor(chart): 提取buildChatGPTChartHtml为共享模块lib/chatgpt-chart-html.js(课题2,备忘录34)——server.js类方法改为转发,函数体逐字节一致仅类方法→独立函数;桌面APP经make/build-pdf-render-assets.mjs逐字节同步同一文件(漂移校验报错),chatgpt_chart渲染两端单一事实源

fix(server): 413 entity.too.large干净JSON响应+content-length盲区观测(PostHog 09-09韩国413=HTML错误页暴露) + requestTimeout=0根除Grok慢上传408(09-06,渲染超时已有应用层动态上限兜底,不动server.timeout防大文件渲染回退) + Claude Imagine widget无前缀设计令牌补齐(SVG var(--text-warning)等消失根因)

feat(pdf): 页脚品牌文案支持插件传入 brandText（唯一事实来源迁至插件 watermark.js，未传回退默认值向后兼容）+ 品牌名统一 XWX Exporter，bump v3.0.0

fix(widget): DOCX图表fallback成数据表格根因修复 — widget渲染浏览器池+CDP有限超时+渲染硬超时+队列超时取消+BrowserPool补位bug+body-parser JSON兜底, bump v2.1.11
