# Clean up any holders / mounts / LVM / crypt devices on the install disk
# before archinstall starts wiping. Idempotent — called once per install attempt
# from the orchestrator's cleanup_disk phase.
#
# Ported verbatim from .automated_script.sh's cleanup_install_disk(). Kept in
# bash because lsblk / findmnt / lvm / cryptsetup are all easier to drive
# here than from Python.
