feat(website): 更新官网至 v0.7.12 并去 AI 味改版

- 版本号/下载链接模板化（VERSION 单点维护），changelog 增 v0.7.12 条目
- 数据修正：模型库 5910 → 7495 / 供应商 212，JSON-LD softwareVersion 同步
- 文案重写：清除一键/开箱即用/一目了然等八股措辞（中英 ~50 处），
  改为具体可验证的说法；英文标题 sentence case
- 视觉降 AI 感：删网格底纹与光晕、主色降饱和、Download 三等宽卡改
  Windows 主推不对称布局、Privacy 改单面板、Features 双列错落
- gh-pages 已随本次改动重新部署
