Function resolve_catalog_package_ref 

pub(crate) fn resolve_catalog_package_ref<FChoose>(
    conn: &DbConnection,
    package_ref: &PackageRef,
    choose_package: FChoose,
) -> Result<CatalogPackage>
where
    FChoose: FnMut(&str, &[CatalogPackage]) -> Result<usize>,

Resolve a package reference to a single catalog package.

Name-based references use the same interactive disambiguation rules as a raw query. ID-based references bypass the chooser and resolve by exact catalog ID only, which keeps package references deterministic when the caller has a unique identifier.
