Architektur: Craftvia-Domänenmodell, Verträge und Team-Schnitte

- Migration 0002_craftvia_domain: 27 Fachtabellen inkl. RLS (enable_tenant_rls)
- TENANT_MODELS (db.ts, backup/topology.ts) um alle Fachmodelle ergänzt
- moduleGuard liefert DB-autoritative Rechte; ServiceCtx für Domänen-Services
- Verträge: Statusmaschine, Events, Nummernkreise, Sichtbarkeits-Scopes,
  Job-Queues + Worker, KI-Provider-Interfaces, Sync-Envelope
- docs/craftvia/ARCHITEKTUR.md mit Lanes, Ownership und DoD

Gate: tsc, lint, build, 22/22 Tests grün.
