🔒️ security(server): 业务接口保护开关与存活探针
- access_key 改用 subtle.ConstantTimeCompare 常量时间比较,防时序攻击 - 新增 server.protect_all 配置:开启后业务接口(/search、/content 等)也要求访问密钥 - 代理路由(/audio/proxy/、/manga/image/)不参与保护,其 URL 由服务端生成不含 key - 新增 /healthz 存活探针(不校验密钥,供容器/反代使用) - openapi.yaml 补 /healthz 定义,Unauthorized 描述说明 protect_all 行为 - 新增 3 个测试:保护开关放行、healthz、错误响应行为
