~x-ai/grok-latest → A (3:1)

A removes a full UI action path (ExpandNewThreadForm handler, enum variant, and the home toolbar POST+) and SSRs #new-thread-ui-slot like room pages, fixing real UX inconsistency and dead complexity. B only rewrites tests.edn to one auto ns-pattern—useful DX hygiene, but a small config change with no product or runtime impact.
