fix: resolve test conflicts and improve data scanner functionality

- Fix multi-threaded test conflicts in AHM heal integration tests
- Remove global environment sharing to prevent test state pollution
- Fix test_all_disk_method by clearing global disk map before test
- Improve data scanner and cache value implementations
- Update dependencies and resolve clippy warnings
