~anthropic/claude-sonnet-latest → B (6:4)

Side B implements a full, working feature end-to-end (CLI `room create` command, RPC handler simplification, event/type cleanup removing unused ThreadVisibility, updated docs and integration/bb tests), representing broader lasting functional and architectural value. Side A is a small, well-tested but narrow bugfix (skip pinned Reddit posts) that is correct and useful but much more limited in scope compared to B's feature-plus-cleanup work.
