+/**
+ * omniroute setup-roo — configure Roo Code (RooVeterinaryInc.roo-cline) for OmniRoute.
+ *
+ * Roo is a VS Code extension (Cline fork). Its live settings live in opaque VS
+ * Code globalStorage, but Roo supports **Settings Import** + an
+ * `roo-cline.autoImportSettingsPath` (VS Code settings.json) that loads a JSON on
+ * startup. So this writes a best-effort import file + wires autoImport (when a VS
+ * Code settings.json exists) + prints the UI steps as the guaranteed path.
+ *
+ * OpenAI-compatible: baseUrl WITH /v1 (Roo appends /chat/completions). The model
+ * must support native OpenAI tool-calling (OmniRoute does).
