feat: install pre-pacman ZFS snapshot hook on ZFS-root systems
archsetup took sanoid from install-archzfs but never ported the pre-pacman snapshot hook, so a ZFS-root install had no transaction-triggered rollback point — the working setup only existed as a hand-placed script on velox, lost on reinstall. Add configure_pre_pacman_snapshots(): a PreTransaction pacman hook plus a self-pruning script that keeps the 10 most recent pre-pacman snapshots (sanoid ignores them — they aren't autosnap_ names). It's gated to ZFS-root and runs late in boot_ux, so the hook doesn't fire during the install's own package operations and the first snapshot is the fresh system.
The script ships as scripts/zfs-pre-snapshot, made ZFS_PRE_* env-overridable so the pruning logic is unit-testable. Unit tests drive it against a fake zfs (creates a snapshot, prunes the oldest past KEEP, ignores non-pre-pacman snapshots, honors the lockfile interval, warns on failure); a Testinfra test asserts the hook and script land on a ZFS install; the orchestrator test pins the new boot_ux substep.
