feat(updater): integrate China-specific feed URLs for better update experience (#177)

- Set PRODUCTION URL to China mirror (http://release.echoplayer.z2blog.com/api/releases)
- Add CN_ALPHA and CN_BETA URLs for Chinese users' pre-release channels
- Simplify AppUpdater logic to use PRODUCTION URL for all stable releases
- Maintain GitHub URLs for non-CN users in test mode
- Improve logging to distinguish China mirror usage
