B adds a real CLI `room create` path and lasting domain simplification (drop ThreadVisibility/RoomState, rooms as HashSet, simpler RoomCreate RPC) wired through server, types, tests, and docs. A only tightens rank-history indexing (1-based/optional → 0-based/expect, UI always links, tests), a correct but narrower consistency fix.
