test(mcp): update test to reflect new MCP sync architecture

Remove MCP-related assertions from sync_codex_provider_writes_auth_and_config
test since provider switching no longer triggers MCP sync in v3.7.0+.

MCP synchronization is now handled independently by McpService,
not as part of the provider switch flow.

+# CC Switch 代理功能使用指南
+
+## 功能介绍
+
+CC Switch 的代理功能是一个本地 HTTP 代理服务器，可以统一管理 Claude Code、Codex 和 Gemini CLI 的 API 请求。主要特性包括：
+
+- **统一代理入口** - 所有 CLI 应用的请求通过本地代理转发
+- **自动故障转移** - 当前供应商故障时自动切换到备用供应商
+- **按应用控制** - 可独立控制每个应用是否启用代理
+- **配置保护** - 自动备份原始配置，停止代理时安全恢复
+
+## 快速开始
+
+### 1. 启动代理
+
+在 CC Switch 主界面，点击右上角的 **Proxy** 按钮，可以看到代理控制面板。
+
+点击 **启动代理** 按钮启动本地代理服务器。代理默认监听 `127.0.0.1:15721`。
+
+### 2. 启用应用接管
+
+代理启动后，你可以选择让哪些应用的请求通过代理：
+
+- **Claude** - 接管 Claude Code 的 API 请求
+- **Codex** - 接管 Codex CLI 的 API 请求
+- **Gemini** - 接管 Gemini CLI 的 API 请求
+
+点击对应应用的开关即可启用/禁用接管。
+
+> **注意**：启用接管后，CC Switch 会自动修改对应应用的配置文件，将 API 端点指向本地代理。原始配置会被安全备份。
+
+### 3. 正常使用 CLI
+
+启用接管后，你可以正常使用各个 CLI 工具。所有请求都会经过 CC Switch 代理转发到配置的供应商。
+
+### 4. 停止代理
+
+当你不再需要代理时，点击 **停止代理** 按钮。CC Switch 会：
+
+1. 安全关闭代理服务器
+2. 自动恢复所有应用的原始配置
+3. 清除代理状态
+
+## 自动故障转移
+
+### 工作原理
+
+代理功能内置了智能故障转移机制：
+
+1. **健康监控** - 实时监控每个供应商的响应状态
+2. **熔断器** - 连续失败 5 次后触发熔断，暂停使用该供应商
+3. **自动切换** - 熔断后自动切换到列表中的下一个供应商
+4. **自动恢复** - 30 秒后尝试恢复熔断的供应商
+
+### 配置故障转移
+
+要使用故障转移功能，你需要：
+
+1. 在对应应用下添加多个供应商（至少 2 个）
+2. 启动代理并启用接管
+3. 当主供应商故障时，代理会自动切换到备用供应商
+
+### 健康状态指示
+
+在供应商卡片上可以看到健康状态指示：
+
+- **绿色** - 供应商正常
+- **红色** - 供应商故障/熔断中
+- **灰色** - 未使用代理或未检测
+
+## 按应用接管
+
+v3.9.0 新增了按应用分粒度控制功能：
+
+- 你可以只接管 Claude，而让 Codex 使用原始配置
+- 每个应用的接管状态独立管理
+- 启用/禁用不会影响其他应用
+
+### 接管状态检测
+
+CC Switch 通过检测配置备份来判断接管状态：
+
+- 存在备份 = 已接管
+- 无备份 = 未接管
+
+这确保了即使 CC Switch 异常退出，重新启动后也能正确识别状态。
+
+## 代理配置
+
+在代理面板中，你可以配置以下参数：
+
+| 参数 | 默认值 | 说明 |
+|------|--------|------|
+| 监听地址 | 127.0.0.1 | 代理服务器绑定地址 |
+| 监听端口 | 15721 | 代理服务器端口 |
+| 最大重试 | 3 | 请求失败时的最大重试次数 |
+| 请求超时 | 120 秒 | 单个请求的超时时间 |
+| 启用日志 | 是 | 是否记录请求日志 |
+
+## 常见问题
+
+### Q: 代理启动失败，提示端口被占用？
+
+A: 默认端口 15721 可能被其他程序占用。你可以：
+- 关闭占用该端口的程序
+- 在代理配置中修改端口号
+
+### Q: 启用接管后 CLI 无法使用？
+
+A: 请检查：
+1. 代理服务器是否正常运行（查看代理面板状态）
+2. 供应商配置是否正确（API Key 等）
+3. 网络连接是否正常
+
+### Q: 如何恢复原始配置？
+
+A: 点击 **停止代理** 按钮，CC Switch 会自动恢复所有应用的原始配置。
+
+如果 CC Switch 异常退出，重新启动后会检测到之前的备份，你可以：
+- 点击停止代理来恢复配置
+- 或继续使用代理功能
+
+### Q: 故障转移没有生效？
+
+A: 请确保：
+1. 配置了至少 2 个供应商
+2. 代理已启动且接管已启用
+3. 故障转移只在代理模式下工作
+
+### Q: 代理会影响性能吗？
+
+A: 本地代理的延迟开销非常小（通常 < 1ms）。但如果启用了请求日志，在高频请求场景下可能会有少量性能影响。
+
+## 技术细节
+
+### 配置文件位置
+
+启用接管后，CC Switch 会修改以下配置文件：
+
+| 应用 | 配置文件 | 修改内容 |
+|------|----------|----------|
+| Claude | `~/.claude/settings.json` | `apiBaseUrl` 指向代理 |
+| Codex | `~/.codex/config.toml` | `[api] baseUrl` 指向代理 |
+| Gemini | `~/.gemini/.env` | `GEMINI_BASE_URL` 指向代理 |
+
+原始配置备份在 CC Switch 数据库中，停止代理时自动恢复。
+
+### 代理模式
+
+代理服务器运行在接管模式下，会：
+
+1. 接收来自 CLI 的 HTTPS 请求
+2. 根据当前供应商配置转发到真实 API 端点
+3. 返回响应给 CLI
+4. 记录请求日志和健康状态
+
+### 数据库表
+
+代理功能使用以下数据库表：
+
+- `proxy_config` - 代理配置
+- `provider_health` - 供应商健康状态
+- `proxy_request_logs` - 请求日志
+- `circuit_breaker_config` - 熔断器配置
+- `proxy_live_backup` - Live 配置备份
