- Added safeIntToUint and safeFloat64ToUint functions to prevent integer overflow in proxy_host_handler.go.
- Updated GetAvailableSpace method in backup_service.go with overflow protection.
- Improved LiveLogViewer tests by using findBy queries to avoid race conditions.
- Adjusted benchmark.yml to handle permissions and increased alert threshold to 175%.
