领域知识上传支持 Word/Excel/PDF/图片：提取正文注入提示词

- 后端 db-sidecar.mjs：新增 async extractDocText 替换 isTextMime/readKnowledgeFile，
  PDF(pdf-parse)/Word(.docx,mammoth)/Excel(.xls/.xlsx,SheetJS) 提取正文并 16k 截断注入，
  图片及老 .doc 返回空串仅登记为参考来源；buildKnowledgePrompt 改为 await extractDocText。
- 前端 KnowledgeStep：上传 accept 放开至 .pdf/.doc/.docx/.xls/.xlsx/image/* 等，
  提示文案补充「Word/Excel/PDF 提取正文，图片仅登记」，文件类徽标「文档」→「文件」。
- 新增依赖 pdf-parse/mammoth/xlsx（纯 JS，无原生编译）。
- design-doc.html 升 v0.23 并登记变更。
