The rebrand commit (deb28452) renamed github.com/FerretDB/wire to
github.com/hanzoai/docdb-wire, but the hanzoai/docdb-wire repo does
not exist. Reverting that rename so the build works at HEAD and so
future merges with FerretDB upstream stay clean.
Per docdb LLM convention, the wire dep stays as FerretDB/wire
upstream. Only the FerretDB project itself is rebranded to docdb.
