Introduces a requiresManifestVersionLookup property to PackageManagerDescriptor to control whether a package manager needs an explicit metadata lookup for tags, ranges, or when no fetchSpec is provided before attempting to fetch the full registry manifest.

This change optimizes manifest fetching by enabling a preliminary metadata lookup for package managers like yarn-classic that require it to resolve tags and ranges to concrete versions.
