-* `ddev-phpmd.rulesets`: Array of PHPMD rulesets to use (default: `["cleancode", "codesize", "controversial", "design", "naming", "unusedcode"]`). Only used when no custom config file is specified.
-* `ddev-phpmd.minSeverity`: Minimum severity level for reported issues: "error", "warning", or "info" (default: `"warning"`)
