v0.7.30

Fixed

• The VS Code extension decides for itself when a .epochix.yaml sets
  nothing. A blank file, one whose every line is a comment, or one holding
  only a document marker sets nothing, as the command line reads it. The
  extension left that to its YAML library, and js-yaml 5 throws on an empty
  document where 4 did not: the panel would have called an empty file "not
  valid YAML". Found by Dependabot's js-yaml 5 pull request failing the
  loader's golden test; three more such files are now in the golden.

Dependencies

• The extension reads .epochix.yaml with js-yaml 5 (from 4), and its
  development tooling is updated (typescript-eslint and two more). The
  dashboard builds with vite 8.3.2 and is tested with the current vitest.
  None of these changes what a run is told or graded; the extension's
  thresholds-file golden test passes unchanged on js-yaml 5.
