feat: 阈值预警/加力钱包/api_key_env/版本跟踪器/一键体检 — bump to v0.7.20

服务端 api.kimi.com/coding/v1/usages 已由绝对 used/limit 行切换为
quota 模型（usages.limit_5h/limit_7d/limit_month_total/limit_month_code，
条目为 used_ratio 0-1 比率 + reset_time），见上游 #3787。

- parse_kimi_coding 优先解析新结构，旧 limits/usage 结构保留为回退
- used_ratio >1 时按已是百分数处理（防御）
- 新 tier id month_code + 前端 planLabel/i18n 中英文案
- 新增 3 个测试：四窗口解析 / 比率防御 / 空窗口回退旧结构

+# KimiSwitch v0.7.18
+
+## 新增
+
+- **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）
+
+## 修复
+
+- 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

+# KimiSwitch v0.7.19
+
+## 适配
+
+- **适配 kimi-code 0.43.0 实验 flag 镜像（7→5）**：移除已转正的 `auto_session_title` 开关（上游 #3749，AI 会话标题不再需要 flag，首轮对话后自动生成、可在重命名处重新生成）。设置页「实验性 flag」、环境变量探测（`get_experimental_env_status`）、中英文案与测试断言同步清理；上游 0.43.0 注册表现剩 5 个 flag： `wait_for` / `tool-select` / `notify_user` / `tower` / `subagent_fork`
+- **兼容性核查结论（无需改动）**：0.43.0 的 wire 持久化重建（#3737）不影响用量统计——`usage.record` / `token_counting.measured` / `context.apply_compaction` / `turn.prompt` 记录全部保留（`turn.prompt` 仅新增可选 `turnId` 字段）；新增配置项 `loop_control.compaction_max_attempts`（#3750）经现有合并式写入验证保存不丢失；MCP `deferred` 字段（#3667）不涉及本应用管理的配置节
+
+## 备注
+
+- 若此前在 `[experimental]` 中显式开启过 `auto_session_title`，残留键会被上游静默忽略，无需手动清理

+# KimiSwitch v0.7.20
+
+## 新增
+
+- **套餐用量阈值预警**：用量配置面板新增「预警阈值 %」（0-100，0 或空 = 关闭）。每次账单查询后，任一百分比用量窗口达到阈值即红色高亮 + ⚠ 标记，低于阈值自动消除；自动查询间隔会周期性重复评估
+- **Kimi For Coding 加力钱包**：0.43.1 起服务端 quota 响应中的 `boosterWallet`（加力钱包）现在解析展示为一行余额（💰 月度用量 / 总额 / 余额，含币种），与四个用量窗口并列
+- **供应商凭证环境变量化（`api_key_env`）**：适配 kimi-code 2.0.0 #3762——供应商编辑页「凭证来源」可切换「直接填写 / 环境变量」，密钥不写进 config.toml；导出时与 `api_key` 互斥；账单查询 / 获取模型列表会实时解析环境变量（变量未设置给出明确错误）；SQLite 新增列（含自动迁移）
+- **Kimi Code 版本跟踪器**：设置页新增「Kimi Code 版本」卡片——本机已装版本（`kimi --version` 检测）、上游最新版本、适配状态徽标（绿已适配 / 黄建议升级 KimiSwitch / 橙部分兼容 / 灰未安装），可一键打开上游 Releases
+- **供应商一键体检**：供应商列表新增「一键体检」按钮——并发探活所有启用供应商的推理端点（`GET /v1/models`）并顺带重新查询账单，每行状态点 + 延迟 tooltip + 顶部汇总。状态判定为三态：账单或探活任一真实通过 = 绿；鉴权失败必红；端点不支持模型列表（404）计中性不误报
+
+## 设置
+
+- **压缩重试次数**：Agent 设置新增 `loop_control.compaction_max_attempts`（上游 0.43.0 #3750，默认 5，0/空不写键）
+- **文件监听开关**：新增 `[watch] enabled` 开关（上游 2.0.1 #3892，2.0.2 起上游默认关闭），并探测 `KIMI_CODE_WATCH` 环境变量
+
+## 适配
+
+- **kimi-code 2.0.2 已适配确认**：wire 记录格式、实验 flag（5 个）、config 模式均无变化；`api_key_env` / `[watch]` / `[database]` 新增配置节经现有合并式写入验证无损往返
+
+## 备注
+
+- 版本跟踪器的「最新版本」查询直连 GitHub，受限网络环境下可能显示 `—`（已装版本与状态判定不受影响）
+- 体检跳过大模型平台类供应商（anthropic / google-genai / vertexai 无 `/v1/models` 路由），显示灰点「未检测」
