refactor: reorganize guide.html sidebar navigation

Old: 10 groups, "快速开始" had 11 items mixing install/config/reference
New: 10 groups with clear separation of concerns:
1. 🚀 快速开始 (2 items: intro + quickstart overview)
2. 📦 安装方式 (6 items: all install methods grouped together)
3. ⚙️ 首次配置 (3 items: post-install setup)
4. 🤖 模型配置 (unchanged)
5. 💬 接入平台 (unchanged)
6. 🎯 技能 (unchanged)
7. 📋 日常使用 (merged "推荐工具" single-item group here)
8. 🔒 进阶部署 (moved env-vars + commands here from FAQ)
9. ❓ 常见问题 (trimmed to FAQ + doctor + uninstall)
10. 📖 关于 (renamed from 官方文档, consolidated)
