openai/gpt-chat-latest → B (3:2)

Side B adds a complete user-facing room creation path to the CLI, wires it through the RPC layer, updates the protocol by removing the unused visibility parameter, simplifies room storage from a HashMap to a HashSet where only existence is needed, and updates tests and documentation accordingly. Side A is a solid targeted bug fix that skips stickied/pinned Reddit posts during import and adds a regression test, but its impact is narrower than the end-to-end feature and API simplification in Side B.
