+//! Wraps the existing [`crate::packagist::fetch_package_versions`] so the
+//! resolver sees the same data either through this trait or via the legacy
+//! direct call. Construction takes ownership of the [`Cache`] handle so
+//! callers no longer thread it through `ResolveRequest` / `LockFileGenerationRequest`.
