fix: rank same-named archives by what they hold

The name step only ranked archive copies by members declared
through archive sub-entries, and the contents an archive entry lists
never reached the resolver, so the first copy indexed won. contents
now ranks copies by crc32, or by member name where the code opens
by name, and the report and both extra passes carry it. With no
layout declared, a primary holding every ROM of the others wins;
two revisions keep the index order.
