Codex 0.164.0: Switch Models and Permissions Inline

Codex 0.164.0 adds inline arguments to /model and /permissions, letting you switch models, reasoning effort, speed, and permission profiles without navigating pickers. Learn a practical workflow for saving those combinations in /presets, plus caveats around unsupported settings and resumed sessions. Also covered: credential masking in supported remote shell sessions, image previews for compatible terminals, preserved CLI configuration overrides, and fixes for queued prompts and failed compaction.
