ben.stull 9462423642 feat(slice-1): platform/db migration runner + migration 0001 (INV-7, §6.3 schema)
Forward-only, fail-stop, advisory-lock-guarded psycopg runner; migration 0001 lays
the account/auth_code/storefront/membership schema. Tests prove migrate-from-empty
and idempotent re-migrate (INV-1 partial) and the INV-4 many-capable shape.
