Add health audit and harden docs CI

[scottsgeorge]

Summary

• add npm-based scripts for lint/test/build plus local serving alongside baseline configs (.editorconfig, .gitignore, CODEOWNERS, LICENSE)
• document golden commands and add HEALTH.md audit with scoring, risks, and readiness notes
• align CI workflows to run the golden commands and archive the built docs artifact

Testing

• npm run lint (pass; npm warns about unknown env config "http-proxy")
• npm run typecheck (pass; placeholder message, same npm warning)
• npm test (pass; smoke check)
• npm run build (pass; rebuilds dist, same npm warning)

Remaining P0/P1

• Dependency/secret scanning and SBOM generation still absent; needs additional tooling enablement
• No automated docs deployment, tagging, or changelog; hosting target not defined
• Docs rely on remote OpenAPI spec without caching/validation
• npm run typecheck remains a placeholder until TypeScript/structured sources exist
