feat(sessions): 一键归档 + 归档用量快照落库 — bump to v0.7.18

- archive_sessions_before：按 updatedAt 截止点批量元数据归档（1月/半月/周/指定日期） - 归档瞬间聚合 wire.jsonl 用量按天×模型快照进 SQLite archived_sessions 表 - 统计合并：文件已删除的归档会话由快照合成 UsageRecord 注入 get_summary/日明细，趋势/热力图/模型统计全兼容且绝不双计 - models-dev 快照同步 2026-09-14（7784 模型）；pricing 测试跟随 deepseek-v4-flash 调价（0.15/0.60） - cargo test 129 通过（含端到端归档→删目录→统计保留用例）、tsc 零错误

+> 实施状态更新（2026-09-13）：**Sub2API 兼容已实现（`balance:sub2api`）**。

+## 适配
+
+- **适配 kimi-code 0.42.0 实验 flag 镜像（9→6）**：移除已转正/删除的 4 个开关（子代理次主力模型——模型池恒开、MiniDB 读模型——改由 `[database]` 配置节、远程控制、搜索 Worker），新增 `notify_user`（实验性 Updates 面板，默认关闭）；环境变量探测清单同步；老配置残留旧键上游静默忽略，无需迁移

+# KimiSwitch v0.7.17
+
+## 新增
+
+- **账单查询适配 Sub2API 中转站（`balance:sub2api`）**：支持 Wei-Shaw/sub2api 面板的余额/额度查询（`GET {base}/v1/usage`），自动复用推理 `sk-` API Key，**无需**网页后台 Access Token；解析三种模式——单 Key 总额度（quota）、5 小时/每日/7 天速率窗口（含重置倒计时）、订阅组日/周/月额度与钱包余额（USD）
+  - 用量配置面板新增「Sub2API 中转站」模板，可选覆盖查询地址（Base URL）
+  - `detect_provider` 家族规则拆分：`codingplan.site` 主域识别为 Sub2API，`ai.codingplan.site` 识别为 NewAPI（修正此前主域被误判为 NewAPI 导致查询 404 的问题）
+- **模型映射「获取模型列表」新增批量选择**：发现列表标题右侧新增「全选 / 取消全选 / 反选」三个按钮，配合已有的已添加标记与「添加选中的」，批量接入中转站模型列表更省事
+
+## 修复
+
+- 修复 `codingplan.site`（Sub2API 面板）走 NewAPI 模板查询必然失败的问题——NewAPI 模板（Access Token + User ID）仍适用于 NewAPI / OneAPI 站点，两者互不影响
+
+## 备注
+
+- Sub2API 查询的金额单位由上游硬编码为 USD；速率窗口标签沿用现有本地化（5 小时 / 每日 / 7 天）

+- **会话管理「一键归档」**：支持按 1 个月前 / 半个月前 / 1 星期前 / 指定日期，一键归档所有最后活跃时间早于所选时间点的会话（一次批量操作，替代逐个选择）；结果反馈已归档 / 跳过数量
+- **归档用量快照落库**：归档瞬间把每个会话的 token 用量与费用按「天 × 模型」粒度快照进 SQLite（`archived_sessions` 表）。之后删除已归档会话（释放磁盘）不再损失历史统计——仪表盘的趋势图、热力图、模型统计、区间合计均会自动合并快照数据，且与现存文件实时统计严格去重（只合并文件已删除的归档会话，绝不双计）

+- models-dev 快照同步至 2026-09-14（7784 模型 / 213 供应商），`public/` 前端静态目录同步；pricing 测试价格断言跟随 DeepSeek 官方调价（deepseek-v4-flash input 0.14→0.15 / output 0.28→0.60）
+
+## 备注
+
+- 归档仍是元数据语义（文件原地保留），删除文件才会触发快照合并；用量配置、账单查询等其余功能不受影响
