Decompose spec 0045 into two iterations. Iteration 1 (engine + registry core): Source::bounds() + window_of, M1FieldSource::bounds(), and the aura-registry lineage module (FamilyKind / FamilyRunRecord / Family, group_families, next_family_id, the three *_member_reports extractors, Registry::append_family / load_family_members) with round-trip and per-name-counter tests. Iteration 2 (CLI surface): aura mc, family-aware aura runs (families / family [rank]), sweep/walkforward family persistence via append_family with --name, and the window_of migration of the manifest-window scans. refs #70
