Go Windsurf Rules

- Apply hexagonal architecture: separate domain, application, and infrastructure layers
- Use wire or fx for dependency injection in large applications
- Add OpenTelemetry traces and metrics from the start; it's hard to add later
- Use pgx directly for PostgreSQL; avoid GORM for performance-critical code
- Use goreleaser for building and publishing Go binaries and Docker images
- Write integration tests with testcontainers-go for real database testing
- Use golangci-lint with a curated config; commit the .golangci.yml file
- Use go work for multi-module monorepos
