feat: initial TrustOS platform scaffold

- FastAPI backend: auth, findings, dashboard, attack paths, footprint, AI translator, risk calculator, PDF report generator
- Next.js frontend: Vault dashboard, login, findings table, finding detail with AI coach, digital footprint, reports
- PostgreSQL data model: tenants, users, assets, findings, risk scores, audit reports, attack paths
- Docker Compose + Dockerfiles for all services
- Demo seed data: Acme Corp with 6 findings and 90-day risk score history
- AI Risk Translator (OpenAI/Anthropic) with plain-English business impact
- Role-based access: executive / it_admin / trustos_admin
- Scope-lock engine: authorization required before any assessment

Stage 1-8 complete: Phase 1 Vault Audit product ready
