Problem

The Docusaurus unit tests (npm run docs:test) are not listed in the PR checklist or any contributor-facing documentation. This means contributors who add artifacts to collection manifests will not know to update docs/docusaurus/src/data/collectionCards.ts, causing CI to fail when adding new skills, agents, or prompts to collections.

Proposed Changes

1. .github/PULL_REQUEST_TEMPLATE.md

Add docs:test to the Required Automated Checks section alongside plugin:generate:

 * [ ] Plugin freshness: `npm run plugin:generate`
+* [ ] Docusaurus tests: `npm run docs:test`

2. docs/contributing/ai-artifacts-common.md — "Adding Artifacts to a Collection"

After the existing step 7 (npm run plugin:generate), add step 8:

+8. Update `docs/docusaurus/src/data/collectionCards.ts` to reflect the new artifact count
+   for the affected collection(s) and `metaCollections['hve-core-all']`, then run
+   `npm run docs:test` to verify.

3. docs/contributing/skills.md — Automated Validation section

Add docs:test to the commands list:

+npm run docs:test             # Validate Docusaurus artifact counts

Acceptance Criteria

• PR template includes npm run docs:test in Required Automated Checks
• docs/contributing/ai-artifacts-common.md collection registration steps include the collectionCards.ts update instruction
• docs/contributing/skills.md Automated Validation section includes npm run docs:test
• All three files pass npm run lint:md
