CI's duplicate-detection step (sliding 5-line window) flagged 4 new
duplicate blocks shared with lib/init/nomad/cluster-up.sh — both used
the same `dry_run=false; while [ $# -gt 0 ]; do case "$1" in --dry-run)
... -h|--help) ... *) die "unknown flag: $1" ;; esac done` shape.
vault-apply-policies.sh has exactly one optional flag, so a flat
single-arg case with an `'')` no-op branch is shorter and structurally
distinct from the multi-flag while-loop parsers elsewhere in the repo.
The --help text now uses printf instead of a heredoc, which avoids the
EOF/exit/;;/die anchor that was the other half of the duplicate window.
DIFF_BASE=main .woodpecker/detect-duplicates.py now reports 0 new
duplicate blocks. Behavior unchanged: --dry-run, --help, --bogus, and
no-arg invocations all verified locally.
