System Monitor

# Description

System Monitor is a real-time terminal-based system monitoring tool built in C++23 using the FTXUI library. It reads from /proc/stat, /proc/meminfo, /proc/loadavg, /proc/uptime, and /proc/[pid]/status to display per-core CPU usage, RAM memory (total, used, free, buffers, cached, swap), load average, uptime, and the top memory-consuming processes. The interface auto-updates every second with color-coded progress bars (green <50%, yellow <80%, red >80%).

$ ./deploy.sh $ git clone
