Provide the admin's ed25519 public key in admin_authorized_keys so the
ssh_hardening role installs it, enabling key-based login (and allowing
ssh_disable_password_auth to be flipped on later).

Add zfs_pool_mode: file|single|mirror.
- file (default): loopback disk image at zfs_pool_file_path — real ZFS with
no spare disk, ideal for a cost-optimized test VM; wipes nothing.
- single/mirror: whole spare disk(s); mirror for production redundancy.
Guard/probe now loops over zfs_pool_disks. Update group_vars, README (modes,
prerequisites, safety), and CLAUDE.md current-focus note.

Some sanoid packages (e.g. on Ubuntu 26.04) don't ship /etc/sanoid, so the
config template failed with 'Destination directory does not exist'. Create
the directory explicitly, and copy the packaged sanoid.defaults.conf into
it (sanoid requires it beside sanoid.conf) so the first timer run succeeds.

'No package matching docker-ce' happens when Docker has no repo for the
VM's release codename (common on non-LTS Ubuntu). Add docker_apt_codename
(defaults to the detected release; override to e.g. noble on non-LTS) and
refresh the apt cache right after adding the repo so index errors surface
immediately instead of as a missing package.

Implements the two decoupled backup streams from docs/06 as an idempotent
Ansible role wired into the host playbook:
- Files: sanoid takes/prunes ZFS snapshots per policy (sanoid_datasets) on
its packaged timer; syncoid replicates offsite (heleos-zfs-offsite),
enabled only when zfs_offsite_target is set.
- DB: heleos-db-backup (nightly systemd timer) walks the deployments dir and
dumps each DB-backed site via `docker exec mariadb-dump` into
db-backups/<customer>/<site>/{daily,weekly,monthly} with rotation
(automysqlbackup-style, adapted for the containerized DB; MYSQL_PWD keeps
the password out of the process list). heleos-db-offsite rsyncs offsite
when db_offsite_target is set.
Streams and schedules are configured in group_vars/all.yml; offsite is
opt-in via the two target vars. Updates doc 06 (implementation note), the
ansible README, and CLAUDE.md status. YAML + templates validated by render.

Idempotent host configuration targeting Ubuntu 24.04 with ZFS on a
dedicated second disk. Role-based platform-infra/ansible:
- base: apt packages, timezone, unattended security upgrades.
- zfs: install ZFS, create pool on a dedicated disk (guarded against
wiping a non-empty disk), create platform datasets + customers parent
per docs/03; docker dataset mounted at /var/lib/docker.
- docker: Docker Engine + Compose plugin, daemon.json written before first
start so the native zfs storage driver initializes on the ZFS data-root;
per-site network address pool preconfigured.
- firewall: nftables inbound default-deny in a dedicated table that never
flushes Docker's rules; container outbound SMTP blocked via a DOCKER-USER
jump applied by a systemd oneshot.
- ssh_hardening: key-first SSH with an anti-lockout assertion, config
validation gate, and the sftponly group for Phase 4 SFTP accounts.
Includes ansible.cfg, requirements.yml, inventory example, group_vars with
safety notes, and a run guide. Real inventory (hosts.yml) is git-ignored.
