fix(release): produce a complete set of archives from runners that exist

- Install the target libc headers next to the aarch64 cross compiler, so a
  dependency carrying C sources can compile them for the target
- Move the macOS builds onto runner images that are still offered, so the
  x86_64 build is scheduled instead of queueing forever
- Collect every archive the run produced rather than the helpers alone, so
  the release carries the CLI it is named after
