Subject: [PATCH] fix: add macOS guard for Codex and fix script/sh quoting

- Codex delegation via delegate.sh now errors on macOS where BSD
  script does not support -c (points user to tmux-session.sh instead)
- Wrap script -c command through bash -c so printf '%q' output is
  interpreted by bash, not /bin/sh (which may be dash)
