Clearer refusal when an artifact cannot be created from a type

When an artifact can't be made from a type in a cloud session, you're pointed at a skill or file instead.

What

When creating an artifact from a type is not available in a cloud session, the refusal now points you at a local alternative ("a skill or a file is fine for that") instead of only saying nothing was created. Failures also report a category alongside the message.

Details
  • The failure payload carries files_error (the message) plus an optional files_error_kind naming the class of failure.
  • A new preamble warns that published artifacts do not honour a <base href> written by the author.
Evidence

so nothing was created; do not retry here

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