Add deep system cache cleaning features

Browse Source 
- Clean memory exception reports (can save 1-2GB)
     - Clean diagnostic tracev3 logs with 30-day retention
     - Clean core symbolication cache when >1GB with timeout protection
     - Clean Aliyun/DingTalk security component logs and caches
     - Use standard cleanup functions with proper validation
