Codex 0.163.0 adds /config search, steer-while-responding, and Daybreak by default

OpenAI's Codex 0.163.0 release lets users search preferences with /config and send follow-up messages while Codex is responding to steer it. Daybreak is enabled by default for eligible accounts, and codex exec can select it with an OpenAI API key when the server offers access.
