✨ feat(manga,device): 漫画免签名兜底与 phone 注册身份选项

- /manga 设备池签名路线全部失败时自动降级 wkbrowser 免签名路线（materials/skeleton 三段策略收集原图直链，无需设备/签名/解密），响应附 source: wkbrowser
- 新增配置 fanqie.device_identity（默认 pad 保持现状；phone 对齐书源真机注册 payload：host_bit 64 + 补 hardware/device_device/fingerprint 字段）
- README 与 openapi.yaml 同步文档，新增 manga_fallback 解析测试

-- **接口缓存** - 命中直接返回，不打上游（Redis 启用时优先走 Redis）
+Redis 启用时为**双层架构**：Redis 热层（TTL=业务缓存时长）+ SQL 持久层（不可变内容固定保留 30 天）。
-- **自动清理** - 定期清理过期缓存（Redis 由 TTL 自动过期）
+
+- **读**：Redis → 未命中查 SQL（命中自动回填 Redis）→ 回源上游
+- **写**：Redis + SQL 双写；搜索/分类等动态短缓存只走 Redis 不落库
+- **防击穿**：singleflight 合并并发未命中请求，同一 key 只有一个请求打上游
+- **自动清理** - 定期按行内过期时间清理 SQL 过期缓存（Redis 由 TTL 自动过期）
 - **数据库压缩** - 支持 VACUUM 操作优化数据库

+## 部署
+
+### Linux 服务器（deploy.sh 一键部署）
+
+```bash
+# 首次：编译 + 部署 + 写入 systemd/nginx 配置
+./deploy.sh v1.0.0 --init
+
+# 日常：拉取代码 + 编译 + 部署 + 重启
+./deploy.sh v1.0.0
+
+# 版本管理
+./deploy.sh --list                # 列出已部署版本
+./deploy.sh --rollback v1.0.0     # 回滚到指定版本
+
+# 服务运维
+sudo systemctl status fanqie
+sudo journalctl -u fanqie -f
+```
+
+部署结构：二进制存于 `/opt/fanqie/bin/`，`fanqie-current` 软链接指向当前版本（保留最近 5 个），systemd 守护 + Nginx 反代，部署后自动做 `/healthz` 健康检查。
+
+首次 `--init` 时若服务器装有 certbot，会自动申请 HTTPS 证书并配置 80→443 跳转（邮箱默认 `admin@域名`，可用 `.deploy.env` 的 `CERT_EMAIL` 覆盖）；续期由 `certbot.timer` 自动完成，续期后经 deploy-hook 重载 Nginx。
+
+### 本地交叉编译
+
+```bash
+make build-linux VERSION=v1.0.0   # 产物 fanqie-v1.0.0-linux，scp 到服务器即可运行
+```
