Make a PortalJS portal harvestable by national/EU/US open-data portals — emit standards-compliant DCAT catalog feeds (DCAT 2/3, DCAT-AP, DCAT-US, national profiles) in JSON-LD, Turtle, and RDF/XML at build, with autodiscovery and per-profile conformance checking. Use when a portal needs to be harvested by data.europa.eu, data.gov, or a national open-data catalog.

Symptom	Cause	Fix
`NO_METADATA_CONTRACT`	`lib/metadata/` not found	Portal predates the metadata-profile contract; scaffold with `portaljs-new-portal` or add `lib/metadata` first.
`NO_DCAT_CORE`	`lib/metadata/dcat.ts` not found	The DCAT-3 core is missing; update the portal template before adding profiles.
`BAD_CONFIG`	`dcat.config.json` is not valid JSON	Fix the syntax and re-run `npm run generate:dcat`.
`UNKNOWN_PROFILE`	Profile id not in the registry	Use one of `dcat-2`, `dcat-3`, `dcat-ap`, `dcat-us`, `geodcat-ap`, `croissant`, `dcat-ap-se`, `dcat-ap-ch`, `dcat-ap-de`, or register a national profile first.
Feed flagged non-conformant	`publisher`/`contactPoint` missing for DCAT-AP or DCAT-US	Ask the user for the publishing organization and contact, add to `dcat.config.json`, regenerate.
DCAT-US SHACL rejects the publisher	Publisher has no IRI (blank node)	Set `publisher.uri` (or `homepage`) in `dcat.config.json`.
`next build` fails after config change	Malformed JSON in `dcat.config.json` or `datasets.json`	Print the build log, fix the JSON, rebuild before reporting success.
