feat: implement Multilevel Queue (MLQ) scheduling algorithm

- Added MLQ scheduling logic in multilevel.ts, including queue selection, preemption rules, and quantum expiration checks.
- Updated SchedulerConfig to include mlqQueues for MLQ configuration.
- Created default MLQ queue definitions for use in presets and process store.
- Modified process store to auto-increment process IDs.
- Enhanced tests for MLQ scheduling, covering selection, preemption, quantum expiration, and integration scenarios.
- Updated existing presets to support MLQ and adjusted process definitions to include auto-incremented IDs.
