# This test runs the REAL _humanize_monitor_codex function (not stubs)
# and verifies graceful stop behavior when .humanize/rlcr is deleted.
#
# Validates:
# - Clean exit with user-friendly message when .humanize deleted
# - No zsh/bash "no matches found" errors
# - Terminal state properly restored (scroll region reset)
# - Works correctly in both bash and zsh
