fix: address mirror review feedback

Browse source 
- scope mirror-token to the mirror host and send it verbatim
- route non-repo mirrors straight to the URL fetch instead of throwing
- authenticate the manifest fetch
- warn on slash branches, and on mirror with PyPy/GraalPy
- memoize mirror validation
- exercise the direct-URL path in the E2E job
