Your team needs to analyze code in a monorepo with 30 services using different languages. How do you configure SonarQube for multi-language monorepo analysis with proper project isolation and reporting?

# Monorepo structure:
# /services/order-api/       (Java + Spring Boot)
# /services/payment-api/     (Java + Spring Boot)
# /services/user-service/    (TypeScript + Node.js)
# /services/notification/    (Python + FastAPI)
# /libs/common-utils/        (Java library)
# /infrastructure/           (Terraform - excluded)

# GitHub Actions: parallel analysis of affected services
