Kilo Code Installer

Usage: install [options]

Options:
    -h, --help              Display this help message
    -v, --version <version> Install a specific version (e.g., 1.0.180)
    -b, --binary <path>     Install from a local binary instead of downloading
        --no-modify-path    Don't modify shell config files (.zshrc, .bashrc, etc.)

Examples:
    curl -fsSL https://kilo.ai/cli/install | bash
    curl -fsSL https://kilo.ai/cli/install | bash -s -- --version 1.0.180
    ./install --binary /path/to/kilo
