/**
 * claude-orchestration-command-router.test.cjs — end-to-end tests for the
 * `gsd-tools claude-orchestration` command surface (#1143).
 *
 * Exercises the full dispatch path: gsd-tools → dispatchCapabilityCommand →
 * routeClaudeOrchestrationCommand → the pure detect/emitter functions.
 *
 * NOTE: runGsdTools() returns { success, output, exitCode, error } — it does
 * NOT throw on a non-zero exit (helpers.cjs). Tests assert `.success` and parse
 * `.output`, and check `.error` on the failure path.
