The live ISO auto-activates LVM/md/swap found on attached drives. The
first hardware bench's SSD still carried a Proxmox VE 'pve' VG, so six
device-mapper nodes sat on sda3 and archinstall died at 12 % with
'unable to inform the kernel of the change ... in use'.
install_run now calls diskprep.release_disk() first: swapoff/umount
leaves-first, dmsetup remove / mdadm --stop for every dm/md node stacked
on the disk (retrying until the stack is gone), wipefs -a on partitions
and disk, blockdev --rereadpt. Steps are logged at the top of the install
log (spawn_archinstall opens it in append mode now). The progress page
names this failure explicitly if it still happens.
