- P1: Product::listing() 分页(WHERE status=1+LIMIT/OFFSET+总数)，ProductController 改用并加翻页器，消除列表全表
- P1: outputSitemap() 加 storage/cache/sitemap.xml 文件缓存(TTL 3600s)，消除每次爬虫全表
- P2: 首页 banner 改 whereLimit('status',1,20)
- P2: asset() 追加 ?v=filemtime 版本串，theme.css 改后自动击穿 1y 浏览器缓存
- P2: nginx 启用 gzip(文本资源压缩)
- P2: Model::count() $val 隐式可空改 mixed(PHP 8.4+ 弃用)
