fix(config): expose forward compact mode switch in settings (#241)

## Summary
- Add `forward_compact_mode` to the `/config` settings item list so the
compact-mode switch is visible in the main settings page.
- Include `forward_compact_mode` in initial config cache keys to keep
switch state consistent on load.

## Verification
- `npm run build` (vite-frontend)

+cd flvx
+ln -sf $(pwd)/skills/flvx-api ~/.agents/skills/
+```
+
+## 配置
+
+设置环境变量：
+
+```bash
+export FLVX_BASE_URL="https://your-panel.example.com"
+export FLVX_USERNAME="admin"
+export FLVX_PASSWORD="your-password"
+```
+
+或使用凭证文件：
+
+```bash
+mkdir -p ~/.flvx
+cat > ~/.flvx/.env << 'EOF'
+export FLVX_BASE_URL="https://panel.example.com"
+export FLVX_USERNAME="admin"
+export FLVX_PASSWORD="your-password"
+EOF
+chmod 600 ~/.flvx/.env
+source ~/.flvx/.env
+```
+
+---
+
+## 工具接入方法
+
+### OpenCode
+
+OpenCode 是命令行 AI 编程助手，支持通过 skills 扩展能力。
+

+export FLVX_USERNAME="admin"
+export FLVX_PASSWORD="your-password"
+
+opencode
+```
+
+**示例对话:**
+```
+你: 查看我的转发列表
+你: 创建一个转发到 192.168.1.100:80 使用隧道 1
+你: 检查节点状态
+你: 查看流量使用情况
+```
+
+---
+
+### OpenClaw
+
+OpenClaw 同样支持 skills 机制。
+
+**安装 skill:**
+```bash
+npm install -g @flvx/skill-api

+
+>>> 查看所有节点状态
+>>> 给用户 alice 分配 50GB 流量
+>>> 导出系统备份
+```
+
+---
+
+### Claude Code
+
+Claude Code 是 Anthropic 官方的命令行工具，支持通过 CLAUDE.md 扩展。
+
+#### 方式 1: 项目级 CLAUDE.md
+
+在项目根目录创建 `CLAUDE.md`：
+
+```markdown
+# FLVX API Skill
+
+你可以通过 REST API 操作 FLVX 面板。
+
+## 环境变量
+- FLVX_BASE_URL: 面板地址
+- FLVX_USERNAME: 用户名
+- FLVX_PASSWORD: 密码
+
+## 认证规则
+- Authorization 头使用原始 JWT token，不加 "Bearer " 前缀
+- 所有 API 使用 POST 方法
+
+## 常用 API
+
+### 登录获取 token
+POST /api/v1/user/login
+{"username": "...", "password": "..."}
+
+### 查看转发列表
+POST /api/v1/forward/list
+Authorization: <token>
+{}
+
+### 创建转发
+POST /api/v1/forward/create
+{"name": "xxx", "tunnelId": 1, "remoteAddr": "1.2.3.4:80"}
+
+### 查看节点
+POST /api/v1/node/list
+{}
+```
+
+**使用:**
+```bash
+cd /path/to/your/project
+claude
+```
+
+#### 方式 2: 全局 CLAUDE.md
+
+```bash
+mkdir -p ~/.claude
+cat > ~/.claude/CLAUDE.md << 'EOF'
+# FLVX Panel Operations
+
+使用 FLVX REST API 操作流量转发面板。
+
+环境变量: FLVX_BASE_URL, FLVX_USERNAME, FLVX_PASSWORD
+调用方式: curl -X POST "$FLVX_BASE_URL/api/v1/..." -H "Authorization: $TOKEN"
+注意: Authorization 不要加 Bearer 前缀
+EOF
+```
+
+#### 方式 3: 复制 SKILL.md
+
+```bash
+cat ~/.agents/skills/flvx-api/SKILL.md >> ~/.claude/CLAUDE.md
+```
+
+**示例对话:**
+```
+>>> 帮我查看 FLVX 面板上有哪些节点
+>>> 创建一个名为 test 的转发，目标地址 10.0.0.1:80
+>>> 查看我的流量使用情况
+```
+
+---
+
+## API 覆盖
+
+| 模块 | 操作 |
+|------|------|
+| 认证 | 登录、Token 管理 |
+| 用户 | 增删改查、流量重置、密码 |
+| 节点 | 增删改查、安装、升级、状态 |
+| 隧道 | 增删改查、用户分配 |
+| 转发 | 增删改查、暂停/恢复、诊断 |
+| 分组 | 用户/隧道分组、权限 |
+| 限速 | 增删改查 |
+| 联邦 | 节点共享、远程节点 |
+| 备份 | 导出/导入 |
+
+## 安全提示
+
+- ⚠️ 环境变量在进程列表中可见
+- 使用 `~/.flvx/.env` 文件并设置 `chmod 600`
+- 添加 `export HISTIGNORE="*FLVX_PASSWORD*"` 防止密码进入历史记录
+- Token 仅在会话内存中缓存，不写入磁盘
+
+## 发布
+
+维护者可通过以下方式发布新版本：
+
+```bash
+# 方式 1: 推送 tag
+git tag skill-v2.1.6
+git push --tags
+
+# 方式 2: GitHub Actions 手动触发
+# 在 Actions 页面运行 publish-skill workflow
+```
+
+需要在 GitHub 仓库设置 `NPM_TOKEN` secret。

+name: flvx-api
+description: Operate FLVX traffic forwarding management system via REST API. Supports user/node/tunnel/forward management, federation clustering, and traffic monitoring. Use when user wants to manage FLVX panel programmatically or via natural language.
+metadata:
+  author: FLVX Team
+  version: "2.1.5"
+  requires_env:
+    - FLVX_BASE_URL
+    - FLVX_USERNAME
+    - FLVX_PASSWORD
+---
+
+# FLVX API Operations
+
+Operate FLVX panel through REST API. All endpoints use POST method and return JSON with `{code, msg, data, ts}` envelope.
+
+## Supported AI Tools
+
+| Tool | Installation | Notes |
+|------|--------------|-------|
+| **OpenCode** | `npm i -g @flvx/skill-api` or `ln -s . ~/.agents/skills/flvx-api` | Auto-loads from `~/.agents/skills/` |
+| **OpenClaw** | Same as OpenCode | Compatible skill format |
+| **Claude Code** | Copy SKILL.md to CLAUDE.md or `~/.claude/CLAUDE.md` | Uses context file instead of skills |
+
+## Prerequisites
+
+Set environment variables before starting:
+
+```bash
+export FLVX_BASE_URL="https://your-panel.example.com"
+export FLVX_USERNAME="admin"
+export FLVX_PASSWORD="your-password"
+```
+
+**Security tip:** Add to `~/.flvx/.env` and source on demand:
+```bash
+mkdir -p ~/.flvx && cat > ~/.flvx/.env << 'EOF'
+export FLVX_BASE_URL="https://panel.example.com"
+export FLVX_USERNAME="admin"
+export FLVX_PASSWORD="your-password"
+EOF
+chmod 600 ~/.flvx/.env
+source ~/.flvx/.env
+```
+
+## Authentication Flow
+
+### Session Token Cache
+
+- Token is cached **only for the current conversation**
+- New conversation = fresh login required
+- Token is NOT written to disk (security)
+
+### Auto-Login Pattern
+
+```
+Before ANY API call:
+1. Check if TOKEN is cached in current session
+   ├─ Yes → Use cached token, proceed
+   └─ No → 
+       1. Read FLVX_USERNAME and FLVX_PASSWORD from environment
+       2. POST /api/v1/user/login with credentials
+       3. Cache response.data.token in session memory
+       4. Proceed with original request
+```
+
+### Login Request
+
+```bash
+curl -X POST "${FLVX_BASE_URL}/api/v1/user/login" \
+  -H "Content-Type: application/json" \
+  -d "{\"username\":\"${FLVX_USERNAME}\",\"password\":\"${FLVX_PASSWORD}\"}"
+```
+
+**Response:**
+```json
+{

+
+## Quick Start Workflow
+
+```
+User request → Check env vars → Auto-login if needed → Call API → Return result
+```

+
+### Bash/curl (with auto-login)
+
+```bash
+#!/bin/bash
+BASE_URL="${FLVX_BASE_URL}"
+USERNAME="${FLVX_USERNAME}"
+PASSWORD="${FLVX_PASSWORD}"
+
+# Login and get token
+TOKEN=$(curl -s -X POST "${BASE_URL}/api/v1/user/login" \

+  -H "Authorization: ${TOKEN}" \
+  -H "Content-Type: application/json" \
+  -d '{}' | jq '.'
+```
+
+### Python (requests)
+
+```python
+import os
+import requests
+
+BASE_URL = os.environ.get("FLVX_BASE_URL")
+USERNAME = os.environ.get("FLVX_USERNAME")
+PASSWORD = os.environ.get("FLVX_PASSWORD")

+    "Authorization": TOKEN
+}
+resp = requests.post(f"{BASE_URL}/api/v1/node/list", headers=headers, json={})
+print(resp.json())
+```
+
+### Node.js (fetch)
+
+```javascript
+const BASE_URL = process.env.FLVX_BASE_URL;
+const USERNAME = process.env.FLVX_USERNAME;
+const PASSWORD = process.env.FLVX_PASSWORD;
+
+// Login
+const loginRes = await fetch(`${BASE_URL}/api/v1/user/login`, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({ username: USERNAME, password: PASSWORD })
+});
+const loginData = await loginRes.json();
+if (loginData.code !== 0) throw new Error(loginData.msg);
+const TOKEN = loginData.data.token;
+
+// Authenticated request - NO "Bearer" prefix!
+const res = await fetch(`${BASE_URL}/api/v1/node/list`, {

+    'Content-Type': 'application/json',
+    'Authorization': TOKEN
+  },
+  body: JSON.stringify({})
+});
+console.log(await res.json());
+```
+
+## Response Handling
+
+**Success:**
+```json
+{"code": 0, "msg": "success", "data": {...}, "ts": 1706659200000}
+```
+
+**Error:**
+```json
+{"code": -1, "msg": "用户名或密码错误", "ts": 1706659200000}
+```
+
+**Pattern:**
+```
+1. Parse JSON response
+2. If code === 0 → return data
+3. If code === 401 → token expired, re-login and retry
+4. If code === 403 → permission denied, need admin
+5. Else → show msg to user as error message
+```
+
+## Permission Model
+
+| role_id | Type | Access |
+|---------|------|--------|
+| 0 | Admin | All endpoints |
+| 1 | Regular | Forward CRUD, own profile, assigned tunnels only |
+
+Non-admin users can only see/modify their own resources.
+
+## Module Reference
+
+| Module | Endpoints | Reference |
+|--------|-----------|-----------|
+| Auth | login, captcha | [auth.md](references/auth.md) |
+| Users | CRUD, reset, password | [users.md](references/users.md) |
+| Nodes | CRUD, install, upgrade, status | [nodes.md](references/nodes.md) |
+| Tunnels | CRUD, user assignment | [tunnels.md](references/tunnels.md) |
+| Forwards | CRUD, pause/resume, diagnose | [forwards.md](references/forwards.md) |
+| Groups | User/tunnel groups, permissions | [groups.md](references/groups.md) |
+| Speed Limits | CRUD | [speed-limits.md](references/speed-limits.md) |
+| Federation | Share, remote nodes | [federation.md](references/federation.md) |
+| Backup | Export/import | [backup.md](references/backup.md) |
+| Config | System settings | [config.md](references/config.md) |
+| Types | TypeScript interfaces | [types.md](references/types.md) |
+| Errors | Error codes | [errors.md](references/errors.md) |
+| Examples | Code samples | [examples/](references/examples/) |
+
+## Critical Rules
+
+1. ⚠️ **NO "Bearer" prefix** - `Authorization: <token>`, NOT `Authorization: Bearer <token>`
+2. **All endpoints use POST** - Including list/get operations
+3. **code === 0 means success** - Any other value is an error
+4. **Traffic units**: User.flow is GB, in_flow/out_flow are bytes
+5. **Timestamps**: All timestamps are milliseconds since epoch
+6. **Token is session-scoped**: Cache in memory only, not on disk
+
+## Common Workflows
+
+### Workflow 1: New User Onboarding (Admin)
+```
+1. POST /api/v1/user/create → Create user with traffic quota
+2. POST /api/v1/tunnel/user/assign → Assign tunnels to user
+3. Tell user their username/password
+4. User logs in and creates forwards
+```
+
+### Workflow 2: Add New Node (Admin)
+```
+1. POST /api/v1/node/create → Register node in panel
+2. POST /api/v1/node/install → Get install command
+3. Run install command on target server
+4. POST /api/v1/node/check-status → Verify node is online
+```
+
+### Workflow 3: Create Forward (Any User)
+```
+1. POST /api/v1/tunnel/user/tunnel → List available tunnels
+2. POST /api/v1/forward/create → Create forward on chosen tunnel
+3. POST /api/v1/forward/diagnose → Verify connectivity
+```
+
+### Workflow 4: Node Maintenance (Admin)
+```
+1. POST /api/v1/node/list → Check node statuses
+2. POST /api/v1/node/releases → Check available versions
+3. POST /api/v1/node/upgrade or /batch-upgrade → Upgrade nodes
+4. POST /api/v1/node/rollback → Rollback if needed
+```

+
+## Response Code Field
+
+| code | Meaning | Action |
+|------|---------|--------|
+| `0` | Success | Use `data` field |
+| `-1` | Business error | Show `msg` to user |
+| `-2` | Server/DB error | Retry or report bug |
+| `401` | Unauthorized | Token expired/invalid, re-login |
+| `403` | Forbidden | Need admin privileges |
+
+## Common Error Messages (Chinese)
+
+| msg | Cause | Solution |
+|-----|-------|----------|
+| 用户名或密码错误 | Wrong credentials | Check username/password |
+| Token已过期 | Token expired | Re-login |
+| 权限不足 | Need admin | Use admin account (role_id: 0) |
+| 端口已被占用 | Port in use | Choose different port or delete conflicting forward |
+| 流量不足 | Out of traffic | Contact admin or upgrade plan |
+| 节点离线 | Node offline | Check node status, run install command |
+| 隧道不可用 | Tunnel disabled | Enable tunnel first |
+| 用户已存在 | Username taken | Choose different username |
+| 参数错误 | Invalid request | Check request body format |
+| 转发数量已达上限 | Forward limit reached | Delete unused forwards or contact admin |
+| 该隧道未分配给当前用户 | No tunnel access | Contact admin to get tunnel assigned |
+
+## Error Handling Pattern
+
+### JavaScript/TypeScript
+
+```typescript
+async function callApi<T>(endpoint: string, data: object): Promise<T> {
+  const res = await fetch(`${BASE_URL}${endpoint}`, {
+    method: "POST",
+    headers: {
+      "Content-Type": "application/json",
+      "Authorization": TOKEN,
+    },
+    body: JSON.stringify(data),
+  });
+
+  const result = await res.json();
+
+  if (result.code === 0) {
+    return result.data;
+  }
+
+  switch (result.code) {
+    case 401:
+      // Token expired - clear and retry
+      TOKEN = null;
+      throw new Error("登录已过期，请重新登录");
+    case 403:
+      throw new Error("权限不足，需要管理员权限");
+    case -2:
+      throw new Error("服务器错误，请稍后重试");
+    default:
+      throw new Error(result.msg || "操作失败");
+  }
+}
+```
+
+### Python
+
+```python
+def call_api(endpoint: str, data: dict = None) -> dict:
+    global TOKEN
+    
+    headers = {"Content-Type": "application/json"}
+    if TOKEN:
+        headers["Authorization"] = TOKEN
+    
+    resp = requests.post(f"{BASE_URL}{endpoint}", headers=headers, json=data or {})
+    result = resp.json()
+    
+    if result["code"] == 0:
+        return result.get("data")
+    
+    if result["code"] == 401:
+        TOKEN = None
+        raise Exception("登录已过期，请重新登录")
+    elif result["code"] == 403:
+        raise Exception("权限不足，需要管理员权限")
+    elif result["code"] == -2:
+        raise Exception("服务器错误，请稍后重试")
+    else:
+        raise Exception(result["msg"] or "操作失败")
+```
+
+### Bash
+
+```bash
+call_api() {
+  local endpoint="$1"
+  local data="$2"
+  
+  local response
+  response=$(curl -s -X POST "${FLVX_BASE_URL}${endpoint}" \
+    -H "Authorization: ${TOKEN}" \
+    -H "Content-Type: application/json" \
+    -d "$data")
+  
+  local code
+  code=$(echo "$response" | jq -r '.code')
+  
+  if [ "$code" == "0" ]; then
+    echo "$response" | jq '.data'
+    return 0
+  fi
+  
+  local msg
+  msg=$(echo "$response" | jq -r '.msg')
+  
+  case "$code" in
+    401) echo "Error: 登录已过期" >&2 ;;
+    403) echo "Error: 权限不足" >&2 ;;
+    -2)  echo "Error: 服务器错误" >&2 ;;
+    *)   echo "Error: $msg" >&2 ;;
+  esac
+  
+  return 1
+}
+```
+
+## Retry Logic with Auto Re-login
+
+```typescript
+async function callApiWithRetry<T>(
+  endpoint: string, 
+  data: object,
+  maxRetries = 1
+): Promise<T> {
+  let lastError: Error;
+  
+  for (let i = 0; i <= maxRetries; i++) {
+    try {
+      if (!TOKEN) {
+        await login();
+      }
+      return await callApi<T>(endpoint, data);
+    } catch (error) {
+      lastError = error;
+      if (error.message.includes("过期") || error.message.includes("expired")) {
+        TOKEN = null;  // Force re-login on next attempt
+        continue;
+      }
+      throw error;
+    }
+  }
+  
+  throw lastError!;
+}
+```
+
+## Validation Errors
+
+When request validation fails, the API returns code -1 with specific messages:
+
+| Scenario | Error Message |
+|----------|--------------|
+| Missing required field | `参数错误` or field-specific message |
+| Invalid port range | `端口范围无效` |
+| Invalid IP format | `IP地址格式错误` |
+| Invalid date | `时间格式错误` |
+| Username too short | `用户名长度不能少于3个字符` |
+| Password too weak | `密码长度不能少于6个字符` |

+### 1. Forward Level
+
+Set `speedId` when creating or updating a forward:
+
+```bash
+curl -s -X POST "${FLVX_BASE_URL}/api/v1/forward/create" \
+  -H "Authorization: ${TOKEN}" \
+  -H "Content-Type: application/json" \

+    "remoteAddr": "10.0.0.1:80",
+    "speedId": 1
+  }'
+```
+
+### 2. User-Tunnel Assignment Level
+
+Set `speedId` when assigning a tunnel to a user:
+
+```bash
+curl -s -X POST "${FLVX_BASE_URL}/api/v1/tunnel/user/assign" \
+  -H "Authorization: ${TOKEN}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "userId": 2,
+    "tunnelId": 1,
+    "flow": 50,
+    "speedId": 2
+  }'
+```
+
+## Example: Create Tiered Speed Limits
+
+```bash
+# Create speed limit tiers
+curl -s -X POST "${FLVX_BASE_URL}/api/v1/speed-limit/create" \
+  -H "Authorization: ${TOKEN}" \
+  -H "Content-Type: application/json" \

+# Run all tests (starts servers automatically)
+python with_server.py -- pytest -v
+
+# Run specific test file
+python with_server.py -- pytest test_auth.py -v
+
+# Run with markers

+### Manual Server Management
+
+If servers are already running:
+
+```bash
+# Set environment variables
+export E2E_BACKEND_PORT=6365
+export E2E_FRONTEND_PORT=3000
+
+# Run tests directly
+pytest -v
+```
+
+### Custom Server Configuration
+
+```bash
+# Custom ports
+python with_server.py --backend-port 8080 --frontend-port 5173 -- pytest -v
+
+# Custom server commands
+python with_server.py \
+  --server "make run" --port 6365 --cwd go-backend \
+  --server "npm run dev" --port 3000 --cwd vite-frontend \
+  -- pytest -v
+```
+
+## Test Markers
+
+| Marker    | Description                              |
+|-----------|------------------------------------------|
+| `@e2e`    | Full end-to-end test with browser        |
+| `@api`    | API-only test, no browser required       |
+| `@auth`   | Test requires authentication             |
+| `@slow`   | Slow running test (>5s)                  |
+
+## Writing Tests
+
+### API Tests
+
+```python
+import pytest
+from utils.api_client import APIClient
+
+@pytest.mark.api
+class TestMyAPI:
+    def test_something(self, authenticated_api: APIClient):
+        response = authenticated_api.post("/some/endpoint")
+        assert response["code"] == 0
+```
+
+### Browser Tests
+
+```python
+import pytest
+from playwright.sync_api import Page
+from pages import LoginPage
+
+@pytest.mark.e2e
+class TestMyFeature:
+    def test_something(self, page: Page, frontend_url: str):
+        login_page = LoginPage(page, frontend_url)
+        login_page.goto()
+        # ...
+```
+
+## Page Objects
+
+Located in `pages/__init__.py`:
+- `LoginPage` - Login form handling
+- `DashboardPage` - Dashboard interactions
+- `UserPage` - User management
+- `NodePage` - Node management
+- `TunnelPage` - Tunnel management
+- `ForwardPage` - Forward management
+- `ConfigPage` - Configuration
+
+## Fixtures
+
+Key fixtures in `conftest.py`:
+- `server_info` - Server configuration
+- `backend_url` / `frontend_url` - Base URLs
+- `page` - Fresh browser page
+- `authenticated_page` - Page with logged-in session
+- `api_client` - API client instance
+- `authenticated_api` - Authenticated API client
+- `auth_token` - JWT token string
+
+## Debugging
+
+```bash
+# Run with visible browser
+pytest -v --headed
+
+# Run specific test with debug output
+pytest test_auth.py::TestAuthentication::test_login_with_valid_credentials -v -s
+
+# Generate HTML report
+pytest -v --html=report.html --self-contained-html
+```
+
+## CI Integration
+
+```yaml
+# Example GitHub Actions
+- name: Run E2E tests
+  run: |
+    cd tests/e2e
+    pip install -e ".[dev]"
+    playwright install chromium
+    python with_server.py -- pytest -v --junit-xml=test-results.xml
+```
