+//! No-op DownloaderInterface stub for installer tests.
+//!
+//! PHP mocks `Composer\Downloader\DownloadManager` directly and asserts its
+//! `install`/`update`/`remove` calls. The Rust DownloadManager is a concrete type
+//! that dispatches to a registered DownloaderInterface, so the equivalent stub
+//! lives one level down: a downloader registered under some dist type that records
+//! the calls it receives and resolves to null, the same way the PHP mock returns
+//! `\React\Promise\resolve(null)`.
