Implement sync_test.go + workload scenarios for fsync, fdatasync, sync, sync_file_range

- Add syncFdatasync, syncSync, syncSyncFileRange scenario functions
- Register sync-fdatasync, sync-sync, sync-sync-file-range in scenarios map
- Add sync_test.go with tests for all 4 sync-related syscalls
- sync is a null_event (no path); others are fd_events
- All use direct SYS_* syscalls on amd64 (no wrapper delegation)
