fix(ci): 修复 frontend-security job 中的 pnpm 安装顺序问题

**问题描述：**
GitHub Actions 在 frontend-security job 中报错：
"Error: Unable to locate executable file: pnpm"

**根本原因：**
setup-node@v4 在尝试使用 pnpm cache 时，pnpm 还未安装

**解决方案：**
1. 调整步骤顺序：先安装 pnpm，再设置 Node.js
2. 升级 pnpm/action-setup 从 v2 到 v4
3. 明确指定 pnpm version: 9

**修改内容：**
- 将 "Set up pnpm" 步骤移到 "Set up Node.js" 之前
- 更新 pnpm/action-setup@v2 → pnpm/action-setup@v4
- 添加 version: 9 配置

**正确的步骤顺序：**
1. Checkout 代码
2. Set up pnpm (指定版本)
3. Set up Node.js (可以使用 pnpm cache)
4. Install dependencies

+Additional security-related options are available in `config.yaml`:
+
+- `cors.allowed_origins` for CORS allowlist
+- `security.url_allowlist` for upstream/pricing/CRS host allowlists
+- `security.url_allowlist.enabled` to disable URL validation (use with caution)
+- `security.url_allowlist.allow_insecure_http` to allow HTTP URLs when validation is disabled
+- `security.url_allowlist.allow_private_hosts` to allow private/local IP addresses
+- `security.response_headers.enabled` to enable configurable response header filtering (disabled uses default allowlist)
+- `security.csp` to control Content-Security-Policy headers
+- `billing.circuit_breaker` to fail closed on billing errors
+- `server.trusted_proxies` to enable X-Forwarded-For parsing
+- `turnstile.required` to require Turnstile in release mode
+
+**⚠️ Security Warning: HTTP URL Configuration**
+
+When `security.url_allowlist.enabled=false`, the system performs minimal URL validation by default, **rejecting HTTP URLs** and only allowing HTTPS. To allow HTTP URLs (e.g., for development or internal testing), you must explicitly set:
+
+```yaml
+security:
+  url_allowlist:
+    enabled: false                # Disable allowlist checks
+    allow_insecure_http: true     # Allow HTTP URLs (⚠️ INSECURE)
+```
+
+**Or via environment variable:**
+
 ```bash
-# 7. Run the application
+SECURITY_URL_ALLOWLIST_ENABLED=false
+SECURITY_URL_ALLOWLIST_ALLOW_INSECURE_HTTP=true
+```
+
+**Risks of allowing HTTP:**
+- API keys and data transmitted in **plaintext** (vulnerable to interception)
+- Susceptible to **man-in-the-middle (MITM) attacks**
+- **NOT suitable for production** environments
+
+**When to use HTTP:**
+- ✅ Development/testing with local servers (http://localhost)
+- ✅ Internal networks with trusted endpoints
+- ✅ Testing account connectivity before obtaining HTTPS
+- ❌ Production environments (use HTTPS only)
+
+**Example error without this setting:**
+```
+Invalid base URL: invalid url scheme: http
+```
+
+If you disable URL validation or response header filtering, harden your network layer:
+- Enforce an egress allowlist for upstream domains/IPs
+- Block private/loopback/link-local ranges
+- Enforce TLS-only outbound traffic
+- Strip sensitive upstream response headers at the proxy

+
+Simple Mode is designed for individual developers or internal teams who want quick access without full SaaS features.

+## Antigravity Support
+
+Sub2API supports [Antigravity](https://antigravity.so/) accounts. After authorization, dedicated endpoints are available for Claude and Gemini models.
+
+### Dedicated Endpoints
+
+| Endpoint | Model |
+|----------|-------|
+| `/antigravity/v1/messages` | Claude models |
+| `/antigravity/v1beta/` | Gemini models |
+
+### Claude Code Configuration
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### Hybrid Scheduling Mode
+
+Antigravity accounts support optional **hybrid scheduling**. When enabled, the general endpoints `/v1/messages` and `/v1beta/` will also route requests to Antigravity accounts.
+
+> **⚠️ Warning**: Anthropic Claude and Antigravity Claude **cannot be mixed within the same conversation context**. Use groups to isolate them properly.
+
+### Known Issues
+
+In Claude Code, Plan Mode cannot exit automatically. (Normally when using the native Claude API, after planning is complete, Claude Code will pop up options for users to approve or reject the plan.)
+
+**Workaround**: Press `Shift + Tab` to manually exit Plan Mode, then type your response to approve or reject the plan.

+## Antigravity 使用说明
+
+Sub2API 支持 [Antigravity](https://antigravity.so/) 账户，授权后可通过专用端点访问 Claude 和 Gemini 模型。
+
+### 专用端点
+
+| 端点 | 模型 |
+|------|------|
+| `/antigravity/v1/messages` | Claude 模型 |
+| `/antigravity/v1beta/` | Gemini 模型 |
+
+### Claude Code 配置示例
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### 混合调度模式
+
+Antigravity 账户支持可选的**混合调度**功能。开启后，通用端点 `/v1/messages` 和 `/v1beta/` 也会调度该账户。
+
+> **⚠️ 注意**：Anthropic Claude 和 Antigravity Claude **不能在同一上下文中混合使用**，请通过分组功能做好隔离。
+
+
+### 已知问题
+在 Claude Code 中，无法自动退出Plan Mode。（正常使用原生Claude Api时，Plan 完成后，Claude Code会弹出弹出选项让用户同意或拒绝Plan。） 
+解决办法：shift + Tab，手动退出Plan mode，然后输入内容 告诉 Claude Code 同意或拒绝 Plan
