gofmt: remove trailing blank lines in client.go

By-model panel gains a segmented 1天/7天/全部 control. Selecting a
range fetches /api/stats?since=<RFC3339> and re-renders only that table
client-side, replicating the human/rate template helpers in JS; the
existing /api/stats since param already drives the server-side filter.

- internal/server/templates/admin.html: filter UI + JS, empty/loading states
- internal/server/server_test.go: render test for the filter controls
- scripts/test-instance.sh: build→start→stop→clean test-instance helper

 # Zhanlu Proxy
 
-一个本地 Go 代理服务，用于读取湛卢插件凭据，按插件认证签名规则请求湛卢上游，并暴露 OpenAI 兼容接口。
+一个本地 Go 代理服务，用于读取湛卢（v1.4.2）插件凭据，按插件认证规则换取模型 API Key，并暴露 OpenAI 兼容接口。
 
 当前实现包含：
 
-- 登录页支持插件默认的移动云手机号验证码登录，成功后自动保存凭据到本地 JSON。
+- 登录页支持插件默认的移动云手机号验证码登录：验证码校验后按插件流程调用 `/api/acepilot/zhanlu/v1/login` 获取用户资料，再通过 SM2 签名调用 `/user/api/v2/external/key/get-or-create` 换取模型 API Key，凭据自动保存到本地 JSON。
-- OpenAI 兼容接口：`/v1/models`、`/v1/chat/completions`。
+- OpenAI 兼容接口：`/v1/models`（优先从 `/gateway/v1/model/info` 拉取模型列表）、`/v1/chat/completions`（携带 `Authorization: Bearer <apiKey>` 请求 `{modelBaseUrl}/chat/completions`）、`/v1/responses`（Responses API，自动转换请求/响应格式，兼容新版 SDK 与 AI 编码工具）。
-- 湛卢签名逻辑：RSA `authorization`、SHA-256 query hash、HMAC-SHA1 `Signature`。
+- 湛卢登录签名逻辑：RSA `authorization`、SHA-256 query hash、HMAC-SHA1 `Signature`，用于 v1.4.2 的 v1/login 认证。
-- 湛卢加密 SSE 响应解密并转换为 OpenAI SSE；非流式请求在本地聚合为 OpenAI Chat Completion JSON。
+- 模型 API Key 换取签名逻辑：SM3 摘要 + SM2 签名（`X-Auth-Signature`/`X-Auth-Timestamp`/`X-Auth-Nonce`）。
+- 上游 SSE 直接透传为 OpenAI SSE；非流式请求在本地聚合为 OpenAI Chat Completion JSON。
 - OpenAI 函数/工具调用：支持 `tools`、`tool_choice`、流式 `delta.tool_calls`、非流式 `message.tool_calls` 以及 `role: tool` 结果续传。
+- Token 消耗统计：流式与非流式请求均解析上游 `usage`，按模型/按日/最近明细写入本地 SQLite（`zhanlu.db`），凭据也一并持久化在同一个库中。管理页提供 `GET /admin/stats` 可视化与 `GET /api/stats` JSON 接口。
+- 可用模型：管理后台新增「可用模型」tab，实时拉取上游 `/gateway/v1/model/info` 返回的模型列表，并提供单模型可用性及首字延时（TTFT）探测（`GET /api/models`、`POST /api/models/test`）。

 请求中的 `tools`、`tool_choice` 会传给湛卢模型。流式响应返回增量 `delta.tool_calls`；非流式响应会把分片聚合为完整的 `message.tool_calls`，并保留 `finish_reason: "tool_calls"`。执行工具后，将 assistant 的 `tool_calls` 和 `role: "tool"` 结果放回 `messages` 再发起请求即可得到最终回答。
 
+### Responses API
+
+代理还兼容 OpenAI Responses API（`POST /v1/responses`），支持使用该 API 的客户端（如新版 OpenAI SDK、Cursor 等 AI 编码工具）直接对接。代理会将 Responses API 请求格式转换为上游 chat/completions 格式，再将响应转回 Responses 格式。

+- 时间、模型、流式/非流式
+- `prompt_tokens` / `completion_tokens` / `total_tokens` / `reasoning_tokens`（思考模型）
+- `cached_tokens`（来自 `prompt_tokens_details.cached_tokens`，提示缓存命中的 token 数）与缓存命中率

+

+- `GET /api/stats`：JSON 接口，支持 `since`/`until`（RFC3339）、`model`、`limit` 查询参数。
+- `POST /api/stats/reset`：清空统计（凭据不受影响）。
+
+设置 `ZHANLU_STATS_DISABLED=true` 可停止写入统计。
+
+## 可用模型
+
+管理后台「可用模型」tab（位于「Token 统计」之后）实时展示当前上游接口返回的模型列表，并提供单模型可用性与延时探测：
+
+- 进入 tab 时自动拉取一次，也可随时点击「刷新」重新获取。
+- 每个模型行可单独「测试」，或点击「全部测试」依次探测所有模型。
+- 探测向上游 `/chat/completions` 发送一条极简流式请求（`hi`），测量首字延时（TTFT，首个 SSE 数据块到达时间）与总耗时，并在收到首个内容块后立即关闭连接，避免消耗额外 token。
+- 探测请求不计入 Token 统计。
+
+对应 JSON 接口（需先登录管理页面）：
+
+- `GET /api/models`：实时返回上游模型列表 `{"ok":true,"models":["GLM-4.7",...]}`。
+- `POST /api/models/test`：请求体 `{"model":"<model_id>"}`，返回 `{"ok":true,"model":"...","available":true,"ttft_ms":123,"total_ms":456}` 或 `{"ok":true,"model":"...","available":false,"error":"...","total_ms":789}`。
+
+探测超时上限为 30 秒（`modelTestTimeout`）；凭据未配置或 API Key 缺失时 `GET /api/models` 与 `POST /api/models/test` 会按需自动换取 API Key，与聊天接口一致。
 
 ## 安全说明
 
-- `credentials.json` 包含明文 `AccessKey`、`SecretKey`、`Token`，请不要提交到仓库。
+- `zhanlu.db` 数据库包含明文 `AccessKey`、`SecretKey`、`Token` 和 `apiKey`，请不要提交到仓库。
-- 默认保存在当前执行目录的 `credentials.json`。
+- 默认保存在当前执行目录的 `zhanlu.db`（建议通过 `ZHANLU_DB_FILE` 指向受保护路径）。
 - 建议设置 `ZHANLU_LOGIN_PASSWORD`，避免公网暴露的 `/admin/login` 被直接访问。
 - 错误响应默认不会返回签名 URL，避免泄露 `AccessKey`、`authorization`、`Signature`。
 - `ZHANLU_DEBUG=true` 时会返回更详细错误，但仍会对敏感 query 参数脱敏。
 
 ## 已知限制
 
-- `ZHANLU_UPSTREAM_PATH` 当前默认值是根据插件分析给出的候选路径，真实环境如果返回 404 或上游错误，需要用实际路径覆盖。
+- 灵犀内网 SSO（`/auth/start`、`/auth/callback`）为备用接口，主流程是移动云手机号验证码登录。
 - 手机号验证码接口可能有风控或频率限制；请按正常登录频率使用。
-- 湛卢上游必须使用 `stream:true`；代理对 OpenAI `stream:false` 请求负责聚合流式响应。
+- 模型网关对 OpenAI `stream:false` 请求由代理负责聚合流式响应。
-- UI 模型名 `glm4.7`、`minimax-m2.5` 会按插件逻辑映射为上游 `glm47`、`minimax-m25`。
-- `zhanlu3` 使用独立的内网 VL Gateway 和 `ZHANLU_VL_API_KEY`，当前代理未接入该特殊分支。
