Build, serve, and diagnose a bx-sites (ortus-boxlang/bx-sites) site - build/serve/clean/search-index, doctor (environment/config health), stats (page/word/blog/search-index/output-size report), and check (broken internal links/images, missing alt text, orphaned pages) against an already-built site/. Use this whenever a user wants to run/troubleshoot a bx-sites build, verify a build actually produced valid output, or get a CI-grade quality gate before deploying. For raw docs/ Markdown checks that don't need a build, use bx-sites-content-quality; for shipping site/ somewhere, use bx-sites-deployment.
