refactor(package): port RootPackageLoader into RootPackageData::from_raw

Mirrors Composer\Package\Loader\RootPackageLoader::load(): converts the
parsed RawPackageData into fully typed RootPackageData with Link objects,
defaulted fields, and trait-based accessors. Composer::package() now
returns RootPackageData instead of RawPackageData, eliminating the
pre-normalised JSON workaround noted in the previous comment.
