+ * omniroute setup-cursor — guide Cursor to use OmniRoute.
+ *
+ * Cursor stores its OpenAI key + "Override OpenAI Base URL" in an opaque SQLite
+ * DB (state.vscdb) with no documented stable schema — NOT safe to file-write.
+ * So this command prints the exact in-app steps (and can list available models
+ * from /v1/models). Note: Cursor's custom base URL only powers the Chat panel;
+ * Composer / inline-edit / autocomplete stay on Cursor's own backend.
