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.
