kagehq/port-kill: A lightweight mac status bar development port monitor

Port Kill is a macOS status bar application built in Rust that monitors development processes running on ports 2000-6000. It provides real-time process detection every 5 seconds, displays a color-coded status indicator (green for 0 processes, red for 1-9, orange for 10+), and allows users to terminate processes individually or all at once through a context menu. The app uses lsof commands for process detection and implements graceful termination with SIGTERM followed by SIGKILL if needed.
