- Add Install button that appears when script files are loaded
- Integrate with existing terminal component for script execution
- Pass correct script path to terminal (scripts/ct/script.sh)
- Close modal when installation starts
- Add proper TypeScript handling for union types
- Install button only shows when CT script is available locally
