openai/gpt-chat-latest → A (4:1)

Side A makes a substantive CLI/API redesign by replacing the old `ingest` flow with explicit `forum post`, splitting forum operations into `list/show/post` subcommands, updating RPC responses, enforcing `--delegate` for CLI posts, and aligning integration tests and documentation with the new command structure. Side B improves maintainability by auto-discovering all `test.*` namespaces in Kaocha, but it is a configuration convenience rather than a functional redesign affecting core project behavior.
