Overview

Package sys provides cross-platform process management utilities.

This package handles low-level OS-specific operations for process group management, signal handling, and process lifecycle control. It abstracts the differences between Unix (PGID-based) and Windows (taskkill-based) process termination strategies.

The primary purpose is to ensure proper cleanup of CLI processes and their children, preventing zombie processes and resource leaks.
