* feat(mirror): add architecture-filtered mirroring support (PROJQUAY-10257)
When architecture_filter is set on a mirror config, copy only the
specified architectures instead of using the --all flag. This preserves
the original manifest list digest for OpenShift compatibility by pushing
the original manifest bytes directly after copying the filtered
architecture manifests.
Key changes:
- Add inspect_raw() and copy_by_digest() methods to SkopeoMirror
- Create manifest_utils.py for manifest list parsing and filtering
- Modify perform_mirror() to use architecture filtering when configured
- Add comprehensive unit tests for the new functionality

* fix(mirror): default media_type to OCI index when None (PROJQUAY-10257)
Prevent InvalidHeader error when get_manifest_media_type() returns None
by defaulting to OCI_IMAGE_INDEX_CONTENT_TYPE in the Content-Type header
of the manifest push request.
