Wire the Step-2 building blocks (import, auth, policies) into
`disinto init --backend=nomad` so a single command on a fresh LXC
provisions cluster + policies + auth + imports secrets + deploys
services.
Adds three flags to `disinto init --backend=nomad`:
--import-env PATH plaintext .env from old stack
--import-sops PATH sops-encrypted .env.vault.enc (requires --age-key)
--age-key PATH age keyfile to decrypt --import-sops
Flow: cluster-up.sh → vault-apply-policies.sh → vault-nomad-auth.sh →
(optional) vault-import.sh → deploy.sh. Policies + auth run on every
nomad real-run path (idempotent); import runs only when --import-* is
set; all layers safe to re-run.
Flag validation:
--import-sops without --age-key → error
--age-key without --import-sops → error
--import-env alone (no sops) → OK
--backend=docker + any --import-* → error
Dry-run prints a five-section plan (cluster-up + policies + auth +
import + deploy) with every argv that would be executed; touches
nothing, logs no secret values.
Dry-run output prints one line per --import-* flag that is actually
set — not in an if/elif chain — so all three paths appear when all
three flags are passed. Prior attempts regressed this invariant.
Tests:
tests/disinto-init-nomad.bats +10 cases covering flag validation,
dry-run plan shape (each flag prints its own path), policies+auth
always-on (without --import-*), and --flag=value form.

invocation shape, flag summary, idempotency contract, dry-run, and
secret-hygiene notes.
