The wire protocol was the last holdout and it was not cosmetic: the Hanzo
Datastore server reads X-Datastore-User, and answers a request bearing
X-ClickHouse-User with 401. Verified against the live server, both directions.
So a client still sending the old headers is not merely off-brand, it cannot
authenticate over HTTP.
Everything else follows: types, dialects, error modules, docstrings and doc
links now name Datastore, and doc URLs point at docs.hanzo.ai/datastore rather
than the upstream vendor's site. Zero occurrences of the old name remain.
Still cut from the pinned upstream version, so behaviour is unchanged.
