feat: add complete development team configuration

Add specialized agent configurations for mockupAWS development:
- @spec-architect: Software architect and specification lead
- @db-engineer: PostgreSQL schema and Alembic migrations
- @backend-dev: FastAPI development and services
- @frontend-dev: React dashboard and UI components
- @devops-engineer: Docker and CI/CD setup
- @qa-engineer: Testing strategy and E2E tests

Update prompt-zero.md with complete team and project structure.
Add prompt-team-standup.md for team kickoff and coordination.

Each agent has detailed configuration with:
- Role and responsibilities
- Technical stack
- Scope and constraints
- Output requirements
- Communication style

+
+## Tables to Implement
+1. **scenarios** - Scenario metadata and state

+4. **aws_pricing** - AWS service pricing by region
+5. **reports** - Generated reports metadata
+
+## Constraints
+- MUST use UUID primary keys

+
+## Best Practices
+- Normalization (3NF)
+- JSONB for flexible metadata
+- Partitioning for large tables (logs)
+- Soft deletes where appropriate
+- Connection pooling
+
+## Migration Rules
+- One logical change = one migration
+- Never modify existing migrations after push
+- Include both upgrade() and downgrade()
+- Test migrations on sample data
