Add custom server config and remember-me login.

Allow runtime API/Web/WebSocket URLs via DataStore, plus a remember-login
toggle that clears tokens when the app stops if it is off.

+# Changelog
+
+## [Unreleased] - 2026-06-11
+
+### Added
+
+#### 自定义服务器配置功能 (Custom Server Configuration)
+- **服务器配置管理**
+  - 新增 `ServerConfigManager.kt` - 使用 DataStore 持久化存储服务器配置
+  - 新增 `ServerConfigHolder.kt` - 全局单例提供运行时配置访问
+  - 支持配置自定义 API、Web、WebSocket 服务器地址
+  - 支持从单个域名自动派生三个 URL（简单模式）
+  - 支持手动配置每个 URL（高级模式）
+  - 重置为默认 Multica 公开服务器功能
+
+- **用户界面**
+  - 登录页面添加"自定义服务器"入口
+  - 设置页面添加"开发者选项 → 自定义服务器"入口
+  - Cupertino 风格的服务器配置页面
+  - 实时配置验证和错误提示
+  - 中英文双语支持
+
+- **依赖注入改造**
+  - `ApiClient.java` 新增 `UrlProvider` 接口
+  - 支持运行时动态切换服务器地址
+  - `MainActivity.java` 和 `ComposePilotActivity.kt` 适配新的 URL 提供方式
+
+- **应用启动优化**
+  - `MulticaApplication.java` 添加配置预加载
+  - 确保 ApiClient 创建前配置已就绪
+
+#### 记住登录状态功能 (Remember Me)
+- **持久化登录选项**
+  - `AuthStore.java` 新增 `rememberLogin()` 和 `setRememberLogin()` 方法
+  - 登录界面添加"记住登录状态"开关（默认开启）
+  - 支持中英文："记住登录状态" / "Remember me"
+
+- **自动登出机制**
+  - `ComposePilotActivity` 新增 `onStop()` 生命周期管理
+  - 未勾选"记住登录"时，应用退出自动清空 token
+  - 勾选时保持登录状态持久化
+
+### Changed
+
+#### 网络安全配置
+- **HTTP 支持**
+  - `app/build.gradle` - 将 `usesCleartextTraffic` 从 `false` 改为 `true`
+  - 支持自托管场景使用 HTTP 协议（包括本地测试）
+  - 允许连接到非 HTTPS 的自定义服务器
+
+#### 登录流程优化
+- 保存配置时会自动清空旧 token，要求重新登录（安全考虑）
+- 重置服务器配置时同样清空 token
+
+### Technical Details
+
+#### 新增文件
+```
+app/src/main/java/ai/multica/app/
+├── ServerConfigManager.kt       # 服务器配置管理（DataStore）
+└── ServerConfigHolder.kt        # 全局配置单例
+```
+
+#### 修改文件
+```
+app/build.gradle                              # DataStore 依赖 + cleartext 流量配置
+app/src/main/AndroidManifest.xml             # usesCleartextTraffic 占位符
+app/src/main/java/ai/multica/app/
+├── ApiClient.java                           # UrlProvider 接口 + 动态 URL
+├── AuthStore.java                           # rememberLogin 存储
+├── MainActivity.java                        # ApiClient 构造注入 UrlProvider
+├── MulticaApplication.java                  # 配置预加载
+└── ComposePilotActivity.kt                  # 服务器配置 UI + 记住登录 UI + onStop
+```
+
+#### 新增依赖
+```gradle
+implementation "androidx.datastore:datastore-preferences:1.0.0"
+```
+
+#### 代码统计
+- 新增代码：约 450 行
+- 修改代码：约 80 行
+- 新增文件：2 个
+- 修改文件：7 个
+
+### Security Considerations
+
+1. **服务器切换安全**
+   - 切换服务器时强制清空 token，防止 token 泄露到错误服务器
+   - 配置保存后要求用户重新登录验证
+
+2. **HTTP 流量警告**
+   - 允许 cleartext HTTP 是为了支持自托管和本地测试
+   - 生产环境建议使用 HTTPS
+
+3. **登录状态管理**
+   - 默认"记住登录"开启，保持用户体验
+   - 提供选项关闭，支持共享设备场景
+
+### User Experience
+
+#### 自定义服务器工作流
+1. 登录页或设置页点击"自定义服务器"
+2. 简单模式：输入域名（如 `example.com`）自动派生三个 URL
+3. 高级模式：手动配置每个 URL（支持非标准端口）
+4. 保存后自动跳转登录页
+5. 使用自定义服务器账号登录
+
+#### 记住登录工作流
+1. 登录时勾选/取消"记住登录状态"
+2. 勾选：关闭应用后保持登录
+3. 不勾选：关闭应用后自动登出
+
+### Known Issues & Limitations
+
+1. **构建环境**
+   - Gradle wrapper 在某些 macOS 环境下可能遇到权限问题
+   - 建议使用 Android Studio 进行构建
+
+2. **服务器兼容性**
+   - 假设自托管服务完全兼容 Multica API
+   - 未实现 API 版本检测和兼容性验证
+
+3. **连通性测试**
+   - 保存配置时仅做 URL 格式验证
+   - 不验证服务器可访问性（运行时连接失败才报错）
+
+### Future Improvements (TODO)
+
+- [ ] 添加服务器连通性测试（保存前验证）
+- [ ] 使用 CompositionLocal 替代全局单例 `ServerConfigHolder`
+- [ ] 实现 API 版本检测和兼容性提示
+- [ ] 配置导入导出功能（便于团队共享）
+- [ ] 多环境预设配置模板
+
+### Testing Checklist
+
+- [x] 简单模式域名派生 URL
+- [x] 高级模式手动配置 URL
+- [x] 重置为默认服务器
+- [x] 配置持久化（应用重启）
+- [x] 登录页服务器配置入口
+- [x] 设置页服务器配置入口
+- [x] HTTP cleartext 流量支持
+- [x] 记住登录状态 UI
+- [ ] 记住登录功能测试（需要编译安装）
+- [ ] 自动登出测试（需要编译安装）
+- [ ] 自定义服务器登录测试（需要自托管实例）
+
+---
+
+## Notes
+
+本次更新主要面向以下用户场景：
+1. **企业自托管部署** - 使用自有服务器运行 Multica
+2. **本地开发测试** - 连接本地开发环境进行调试
+3. **共享设备使用** - 支持不记住登录状态，保护隐私
+
+所有功能均保持向后兼容，默认使用 Multica 公开服务器，普通用户无感知。
