administrator 48c102d2a4 feat(convert): integrate process metrics into JSON and SQLite converters
- add process_metrics function to record peak RSS and CPU time
- update JSON converter to include metrics in completion marker
- modify SQLite converter to utilize new metrics for performance tracking
- enhance storage size updates with locking mechanism for concurrent access
