style: gofmt alignment in library_browse_test — #367

One space. `name:` had to align with `query:` inside a composite literal where
both sat on their own lines.

Found via `docker run golang:1.25-alpine gofmt -l`, which is the actual point
of this commit: gofmt is available here the same way sqlc is, and there is no
reason to have let CI discover a formatting nit. Whole tree verified clean, not
just this file.

The substance of 1126bfcf was already sound — verify-generate, vet and the full
integration suite passed, so the genre-splitting behaviour holds against a real
database. Only the formatter objected.
