## Notes

- Infrastructure module for environment configuration management
- Uses CliService for CLI output (appropriate for this use case)
- Uses tracing::warn for logging YAML sequence skips
- Single internal dependency: systemprompt-logging
- `build_validate_configs` uses `#[allow(...)]` for build.rs-specific patterns (println, exit)
