Subject: [PATCH] fix: set DSG_APP_ID to prevent self-identification deadlock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set the DSG_APP_ID environment variable to ApplicationManagerConfig
before initializing the application. This prevents the application
manager from calling its own Identify interface when accessing its own
dconfig, which would cause a deadlock.

Log: Fixed a potential deadlock issue when the application manager
accesses its own configuration

Influence:
1. Test application manager startup and initialization
2. Verify that the application manager can read its own dconfig without
hanging
3. Test interaction with other DSG applications to ensure environment
variable doesn't interfere
4. Monitor system logs for any identification-related errors during
startup

fix: 设置DSG_APP_ID环境变量防止自身识别死锁

在应用程序初始化之前设置DSG_APP_ID环境变量为ApplicationManagerConfig。这
可以防止应用程序管理器在访问自身dconfig时调用自己的Identify接口，从而避
免死锁发生。

Log: 修复了应用程序管理器访问自身配置时可能出现的死锁问题

Influence:
1. 测试应用程序管理器的启动和初始化过程
2. 验证应用程序管理器能够正常读取自身dconfig而不出现挂起
3. 测试与其他DSG应用程序的交互，确保环境变量设置不会产生干扰
4. 监控系统日志，检查启动过程中是否有识别相关的错误
