✨ feat(api): 新增榜单书架历史与搜索续传并重构正文缓存链路
- 新增 /rank 免签名榜单接口(多域名容错)、/bookshelf 与 /read-history(sessionid 登录态,书架支持分组过滤) - 搜索重写:翻页透传上游 passback/search_id/next_offset/corrected_query 并按 book_id 去重,15~20 位纯数字关键词直查详情(ID 直搜) - 删除 /login/check 登录校验端点(login.go、路由与文档同步移除,sessionid 说明改为直接供书架/历史使用) - 正文链路重构:singleflight 合并同章节并发回源防击穿,缓存与解析解耦统一在出口处理,decodeContentBody 按 crypt_status 分支并兜底 500003 明文 - 缓存层:SQL 持久层 TTL 与业务 TTL 解耦(不可变内容过期后由 SQL 回填),动态短缓存只走 Redis,withCache 合并并发 miss - 密钥池:KeyTs 随正文请求上传降低密钥不匹配重试,密钥超 24 小时异步刷新并防刷新风暴,last_used_at 批量落库 - 签名补 X-Helios(与 X-Ladon 同值,对齐书源实现);设备注册版本号统一走 ClientVersionCode/Name - 分类 landing 透传新版标签 selected_items;multi-detail 批量详情供书架/历史复用 - README 与 openapi.yaml 补充新接口文档
