./scripts/build-app.sh
cp -r .build/release/PortKiller.app /Applications/
open /Applications/PortKiller.app

PortKiller uses platform-specific commands to scan for open ports:

Linux/macOS:

ss -tlnp  # or lsof -iTCP -sTCP:LISTEN -P -n

Windows:

netstat -ano

When killing a process, it first tries graceful termination (SIGTERM on Unix), then forces it (SIGKILL) if needed.
