feat(sdk): 实现动态服务端点配置和环境切换功能

- 移除硬编码的基础URL常量，改为可配置的服务端点
- 添加ServiceEndpointRegistry用于统一管理所有服务端点地址
- 实现ApiClient支持多基础URL的Retrofit实例缓存机制
- 新增XuqmSDK.configureServiceEndpoints等方法用于运行时切换环境
- 为sample-app添加SampleEnvironmentConfig支持本地联调环境切换
- 创建独立的IM、Push、Update SDK模块并集成服务端点配置
- 更新文档说明如何进行联调环境切换操作

+### 3. 切换联调环境
+
+默认使用外网域名。若要本地联调，可在 `Application.onCreate()` 里切换：
+
+```kotlin
+XuqmSDK.useLocalServiceEndpoints("10.0.2.2") // Android Emulator
+// 物理设备可改成你的电脑局域网 IP
+```
+
+如果是 sample-app，也可以直接调用：
+
+```kotlin
+SampleEnvironmentConfig.useLocalhost("10.0.2.2")
+```
+
+切换后，HTTP API 会立即走新端点；如果 IM 已登录，SDK 会自动重新连接。
