"""Backfill new awaiting_cert / awaiting_ship states for mid-flight jobs.

Spec: docs/superpowers/specs/2026-05-25-post-shop-cert-shipping-job-states-design.md

Rules:
  - in_progress + all steps terminal + draft cert exists → awaiting_cert
  - in_progress + all steps terminal + no cert required → awaiting_ship
  - done jobs LEFT ALONE — historically completed (already shipped)

Idempotent: re-running on a fresh upgrade is a no-op because no
in_progress job will match the all-terminal predicate after the first
run. Pass 1 and Pass 2 are mutually exclusive (the cert-existence
sub-queries are inverses).
