Update proxy to Zhanlu v1.4.2 provider flow

The 1.4.2 extension replaced the old signed/encrypted chat gateway with an
OpenAI-compatible aigateway. Align the proxy with the new flow:

- Use ecloud.10086.cn login/model base URLs, zhanlu_ide plugin headers and
  v1.4.2 plugin version
- Provision the model API key via SM2-signed get-or-create after v1/login
  profile fetch; store api_key/model_base_url/email in credentials
- Chat via Bearer apiKey against {modelBaseUrl}/chat/completions with plain
  OpenAI SSE passthrough; fetch /v1/models from the gateway model-info endpoint
- Force HTTP/1.1 upstream (gateway drops HTTP/2 ALPN negotiation with EOF)
- Drop obsolete AES body encryption, model name mapping and vscode headers

 # 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。
-- OpenAI 兼容接口：`/v1/models`、`/v1/chat/completions`。
-- 湛卢签名逻辑：RSA `authorization`、SHA-256 query hash、HMAC-SHA1 `Signature`。
-- 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。
+- 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`（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`）。
+- 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。
+- 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。
