fix: resolve semantic merge conflicts from refine-plan + zenus/main merge

- Fix heredoc delimiter mismatch in loop-codex-stop-hook.sh (opening
  AGENT_TEAMS_FALLBACK_EOF vs closing WORKTREE_TEAMS_FALLBACK_EOF)
- Update codex-worker.sh to use renamed DEFAULT_CODEX_MODEL/EFFORT
  variables from refine-plan's loop-common.sh (was DEFAULT_CODEX_WORKER_*)
