oras-go: Arbitrary file write outside file.Store root via symlink-chain bypass in tar extraction (pushDir)

Summary The content/file.Store in oras-go v2 unpacks OCI layer tarballs when a descriptor carries io.deis.oras.content.unpack=true. The extraction routine validates symlink targets purely lexically filepath.Join and, for regular files placed directly at the extraction root, skips the parent-symli...
