Support distributions that ship a full .img (Raspberry Pi OS, moode, RetroPie, Manjaro ARM) rather than a rootfs tarball, by loop-mounting the image and copying its boot + root partitions into a fresh LUKS container. - distributions.yml/catalog.py/choosers.py: raspios catalog (lite64/desktop64/ lite32 via the stable _latest redirects) + choose_raspios. - plan.py: source_url override so a _latest redirect downloads under an .img.xz name that decompress_command recognises. - transfer.py: transfer_disk_image (loop-mount -> repartition -> LUKS -> rsync copy with progress, cp fallback -> fix boot fstab); transfer_image gains interactive= and routes encrypted non-arch images here; download_image gains force_prompt. - loopimg.py: losetup attach/detach/partition helper. - fsutil.drop_fstab_mount + register_encrypted_root: replace a stock image's existing / fstab line instead of colliding with it. - encryption.configure_encryption returns the onion address.
