Codex CLI installs a persistent, self-updating background daemon by default

Codex CLI, a command-line interface for OpenAI's Codex AI model, has been updated to install a persistent, self-updating background daemon by default. This change is intended to improve performance and ensure that users have access to the latest model updates. The daemon is designed to run in the background, automatically updating the Codex model and providing users with the most current functionality. The change has been implemented in the latest version of the Codex CLI, and users can opt-out of the daemon by running the command 'codex config set daemon false' or setting the environment variable 'CODEX_DAEMON=false'.
