style: rustfmt after the registry domain migration

The release gate failed cargo-fmt. The domain that replaced the IP-based
registry is longer, pushing several test assertions past the width limit, so
rustfmt wanted to re-wrap them. Pure line re-wrapping — no semantic change.

Caught by the pre-flight gate rather than after tagging, which is what it is
for.
