- Added get_cpu_usage() function to sample CPU percentage - Updated profile_resources() to profile both memory and CPU - Modified run_program() to track CPU usage alongside memory - Updated output format to show CPU statistics - Summary now displays: Time, Memory (avg/peak), CPU (avg/peak) - Both memory and CPU are sampled every 10ms during execution
