Build three new DDD modules following existing CQRS patterns:
- Inquiries: CRUD endpoints for buyer consultation requests with agent notification support
- Leads: Full lead lifecycle management with status state machine and conversion tracking
- Agents: Quality score calculation (event-driven on review changes) and dashboard stats API
All modules include unit tests (14 test files, all 797 tests pass).
