+/**
+ * Vendored type definitions for the Stackbilt scaffold-response contract.
+ *
+ * These types are structurally copied from @stackbilt/contracts to avoid
+ * a file: workspace dependency on an unpublished sibling repo. They are
+ * type-only (erased at compile time, zero runtime cost) and are used
+ * internally by http-client.ts — they are NOT re-exported from the public
+ * CLI surface in src/index.ts.
+ *
+ * When @stackbilt/contracts is properly published to npm, this file can be
+ * deleted and http-client.ts can re-import from the real package.
+ *
+ * Upstream source (as of @stackbilt/contracts@0.1.0):
+ *   contracts/dist/scaffold-response/scaffold-response.contract.d.ts
+ *
+ * Type aliases follow the upstream naming convention with the `Type` suffix
+ * (e.g. `ScaffoldFile` → `ScaffoldFileType`), matching the re-exports in
+ * contracts/dist/scaffold-response/index.d.ts.
