/**
 * Regression tests for bug #1991
 *
 * Cline is listed in GSD documentation as a supported runtime but was
 * completely absent from bin/install.js. Running `npx @opengsd/gsd-core`
 * did not show Cline as an option in the interactive menu.
 *
 * Fixed: Cline is now a first-class runtime that:
 * - Appears in the interactive menu and --all flag
 * - Supports the --cline CLI flag
 * - Writes .clinerules to the install directory
 * - Installs gsd-core/ engine with path replacement
