0c621f60ae fix(session): mount the boot FAT at /boot/firmware on Bookworm
Raspberry Pi OS Bookworm keeps the FAT boot partition at /boot/firmware, where
the raspi-firmware post-update hook syncs the initramfs. Binding it at /boot in
the chroot sent update-initramfs's output to the ext4 root, so the firmware
booted a stock initramfs without cryptsetup -> (initramfs) emergency shell, no
LUKS prompt. boot_bind_target() detects the layout and binds (and unmounts) the
FAT at the right place; legacy single-FAT layouts still use /boot.

68ea39b784 chore(session): harden chroot package installs (PATH + apt-get update)
- chroot_bash exports a Debian-safe PATH so /usr/sbin tools (update-initramfs,
  useradd, chpasswd, ...) resolve inside the chroot instead of failing with
  code 127.
- install_packages runs apt-get update before install (a stock image ships
  stale lists whose superseded .deb URLs 404) and non-interactive
  apt-get install -y; pacman gains -Sy for the same index-refresh reason.

9b7a34989d feat(image): distro-agnostic remote unlock via initramfs backends + Debian support
Split the mkinitcpio-only remote-LUKS-unlock path into an InitramfsBackend
ABC with a get_backend() dispatch, and add the initramfs-tools backend for
Debian / Raspberry Pi OS.

- base.py: six-step backend contract; encryption.py becomes a thin,
  distro-neutral sequencer (get_backend by distribution).
- initramfs_tools.py: crypttab `none luks,initramfs`, cmdline rewritten to
  root=/dev/mapper + ip=::::host:eth0:dhcp, dropbear-initramfs
  authorized_keys, update-initramfs -k all (no build-host uname leak).
- shipped hooks (configuration/initramfs-tools/*): single-hop non-anonymous
  onion, libnss DNS baking, sed-not-source DHCP, kill-tor-before-pivot.
- shared offline onion keygen in keygen.py; tor.py removed (logic moved to
  mkinitcpio.py).
- raspios added to the apt distro family (session.py, raspberry.py).

ccdef065df refactor!: port shell scripts to Python package
Bash scripts were untestable and duplicated device/LUKS/mount logic;
the lim/ package centralizes it behind one subprocess wrapper and a
YAML image catalog (single point of truth).

BREAKING CHANGE: scripts/*.sh removed. Use `lim --type <cmd>`; new
types mount/umount/single-boot/raid1-boot/lock/unlock/import/export
replace direct script calls. --extra is deprecated and ignored.

- distributions.yml + lim/catalog.py hold the image catalog (PyYAML)
- pytest suite: 102 tests with mocked subprocess (tests/unit) and a
  250-line max file-length guard (tests/lint)
- ruff strict (select ALL), GitHub Actions CI, Dependabot; Travis gone
- Makefile: install (symlink ~/.local/bin/lim) and test targets
- fixes over bash: SUDO_USER-aware chown, mmcblk/nvme partition paths,
  sha512 checksum support, whole-pipeline failure detection, blkid
  UUID fallback for pre-mounted images, conditional fstab seeding for
  PARTUUID/LABEL images, clean errors for missing binaries
