The researcher now reuses the current/already-open document only when the
user explicitly asked for it, OR the page is empty/near-empty AND its title
matches the research topic; otherwise it creates a new document.
- Rewrite the reuse rule in the WHERE TO WRITE THE RESULT section
- Reword "Create this document" -> "Set up this document" so it fits both
the create-new and reuse-current-empty cases
- Apply identically to bundles/research/ru.yaml and en.yaml
- Bump researcher version 3 -> 4 in index.yaml; refresh content-hashes.json
