Subject: [PATCH] ST-cmowjewfg: Test: parser geeft hint bij
 markdown-in-frontmatter

Voeg twee Vitest-cases toe:
- hints when markdown sneaks into frontmatter: fixture met [unclosed op
  een genummerde markdown-regel triggert YAMLParseError op die regel
  (plain lijst zonder unclosed flow parset als geldig YAML)
- omits hint for non-markdown yaml errors: unclosed bracket zonder
  markdown-patroon geeft geen hint
