# Setup helper: install-node — bundles Node 22 install into one idempotent
# script so /new-setup can run it without needing `curl | sudo -E bash -` in
# the allowlist (that pattern is inherently unmatchable — bash reads from
# stdin, so pre-approval can't inspect what's being executed).
#
# The script itself is the allowlisted unit; the pipes and sudo live inside
# it. Pure bash by design — runs before Node exists on the host.
