.forgejo/workflows/iso.yml runs `task build-installer-iso` on a runner
labelled iso-builder (x86_64, root podman) and uploads the ISO to MinIO
under installer/<commit>/ and installer/latest/.
For unattended runs, the Taskfile now only uses sudo when not already root
(CI runners often lack it), and OUTPUT_DIR is absolute so the bind mount
into bootc-image-builder doesn't depend on relative-path support.
