端口: - 服务端口 8000 → 7329 - 前端开发端口 5173 → 7330 安全: - CORS 收紧为白名单，关闭 credentials - SPA 路由白名单完善 - 前端 XSS 转义 可靠性: - 时区统一为 datetime.now(timezone.utc) - 文章入库改为内存去重 + 增量计数 - OPML 导入改为 body 参数接收 - OPML 导出 URL XML 转义 - 首次抓取改为 BackgroundTasks 异步 - articles.py HTTPException 移到顶部 import - FTS5 异常显式日志 - FTS5 查询加引号包裹防布尔注入 - 中文摘要支持中文标点 - 去掉未使用的 hashlib import 部署: - Dockerfile 锁 python:3.12.7-slim - requirements 锁定具体版本 - healthcheck 不用 curl（镜像里没有） - docker-compose 使用 .env 文件 - 新增 .env 配置文件
