The --uninstall flag now removes: - Unified pulse-agent (service, binary, logs) - Legacy pulse-host-agent (service, binary, logs) - Legacy pulse-docker-agent (service, binary, logs) - Agent state directory (/var/lib/pulse-agent) - All related log files Works on Linux (systemd), macOS (launchd), and other supported platforms.
