feat: 品牌升级(知冶→战知) + 应用工具广场重构 + 新增工具集成
品牌升级： - 全站品牌从"知冶"更名为"战知" - 更换 favicon、侧边栏 logo、登录页 logo - 更新登录页标语和首页欢迎语 应用广场重构： - 从后端数据库驱动改为前端静态配置，按分类 tab 展示 - 新增工具卡片 UI，支持 logo 图片和 emoji 图标 新增工具部署： - Stirling PDF (端口18080) - PDF 处理工具箱 - Excalidraw (端口18081) - 手绘风格白板，集成 AI 绘图 - TrWebOCR (端口18083) - 中文离线 OCR - LibreTranslate (端口18084) - 中英翻译引擎 - PPTist (端口18085) - 在线 PPT 编辑器 - PPTist AI 后端 (端口18086) - 对接 deepseek-v3 生成大纲/PPT/写作 - Excalidraw AI 代理 (端口18082) - 对接 deepseek-v3 生成 Mermaid 图 其他： - 智能场景仅保留"选题推荐" - vite 代理配置增加 /pdf/ 和 /draw/ 路由 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
