Adds four audit scripts (module health, inter-module coupling, per-function cognitive complexity, D3 treemap) with generated reports under docs/ and an iframe-embedded workbench app at /admin/complexity. Reports regenerate weekly via the module-health GitHub Action. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
