Whiteboard artifacts get short titles

You'll notice
Useful2 Signal1
Artifacts

Whiteboard artifacts are now just titled "Whiteboard" instead of a long phrase.

What

The whiteboard skill now titles its artifact Whiteboard by default instead of a long explanatory phrase, in the page template, the publish fallback and the merge-state default.

Details
  • The --title guidance now asks for a short topic name followed by the word "whiteboard", for example "Ingest pipeline whiteboard", and forbids appending an explainer after a dash or colon.
  • The helper's error text was updated to match, and the prototype skill's publish instruction now also asks for a short stable title.
Evidence

fail('--title needs the board\'s name (e.g. "Ingest pipeline whiteboard"), got '

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
