1. Fix segmentation fault during --list due to uninitialized memory (added memset to malloc calls). 2. Fix negative width specifier in printf within print_bench_types_cpu. 3. Add missing cleanup functions: exit_benchmark, free_hardware, free_benchmark_cpu, free_cpu_info, free_config. 4. Fix memory leaks in main.cpp and arch.cpp.

This PR addresses several critical stability issues identified while testing the project.
Changes:
memsetto allmalloccalls for core structures (benchmark,benchmark_cpu, andcpu). This prevents segmentation faults during cleanup by ensuring pointers areNULLunless explicitly initialized.print_bench_types_cpuwhere a negative padding width was passed toprintf.exit_benchmark,free_hardware, etc.) and added them to the execution paths inmain.cppto prevent memory leaks.init_benchmark_cpuwherethread_setwas not being freed.Fixes #30
