历史条目的图标原先写死 fas fa-globe，整栏都是地球图标。 - 新增 history-server/favicon.go：后台抓取每个 host 的 favicon 并缓存到 data/item-icons/，命中后 conf.yml 写本地文件名，与手工图标同一套解析。 抓取顺序 <host>/favicon.ico → 首页 <link rel=icon>；3 个 worker， 失败 6 小时后再试；完成后合并触发一次 conf.yml 重建。 - 只缓存 Dashy 能渲染的格式：其 isImage() 白名单是 [svg,png,jpg]， 写 .ico 进去完全渲染不出来。因此 .ico 先抽内嵌 PNG，若是传统 BMP/DIB 编码则解码后转 PNG（Google 这类站点只给老式 .ico）。 - 内网地址用 host:port 区分（不同端口的服务不再共用一个图标），且只直连； 外网站点直连失败时自动复用 SearXNG outgoing.proxies 的代理， 也可用 NAVI_FAVICON_PROXY 覆盖。 - 修掉一个真实缺陷：导航项都没有访问数据时，原来会提前 return 并把 「历史访问」清成只剩安装入口 —— 只浏览站外站点时真实历史会整个消失。 现在只冻结「常用服务」，历史照常生成。 - Dockerfile 去掉 # syntax=docker/dockerfile:1：该指令会让 BuildKit 去 pull docker/dockerfile 前端镜像，无外网环境直接构建失败；本文件未用 BuildKit 语法。 实测：6/6 站点（含 google.com 的 DIB 型 ico、github.com、docker.com、 news.ycombinator.com 与两个内网服务）均得到真实图标，页面 naturalWidth>0。
