chore: name it equalify-iris-bench, everywhere it says its own name
The repo and folder are now equalify-iris-bench, matching equalify-iris.
Renaming those alone would leave the name wrong in the places that
actually travel: the User-Agent every download in the corpus sends to
someone else's server, the clone line in the README, the package name, and
the report's own header. GitHub keeps a redirect from the old path, so
existing clones still fetch — but the remote URL is worth updating too.
