This script provides a system-wide installer for Cursor, the AI-first code editor.
It was originally inspired by install-cursor.sh, but as Cursor's release page and API changed, the original script no longer works reliably.
We adapted and improved the script to ensure it stays functional with the latest Cursor releases.
