A single fix, but a load-bearing one: S3 offload over TLS.
The attohttpc client pulls in rustls, and rustls insists on exactly one active
crypto provider. Two were being linked in, so provider selection was ambiguous
and HTTPS requests to the bucket could not complete. This release pins rustls to
one provider, restoring https:// endpoints.
The story does not quite end here — a follow-up in 0.8.1 proves the TLS path end-to-end against a live MinIO server and hardens the provider guard that this release put in place.
