Imports read `datastore_driver`, distribution `datastore-driver`, so nothing has to import another product's name to talk to Hanzo Datastore. Cut from upstream 0.2.9 — the version this stack already ran — rather than from upstream HEAD, so it is a PURE RENAME with no behaviour change. Forking from HEAD would have dragged versions along with the name (connect alone jumped 0.8.17 -> 1.6.0, a major), which is a different and much riskier change wearing a rename's clothes. X-ClickHouse-* headers are untouched: they are wire protocol the server sends and expects, and a different token shape from the module name.
