Search Studocu institutions by name when establishing or correcting education context (onboarding / context setup). Do not require this before every document search. Structured results include id, name, type, region_code, and country for follow-up tools. When talking to the user, present name/type/country/region only — do not show internal IDs. Auto-pick a clear top match; if the shortlist is ambiguous, ask the user to choose by name. Resolved IDs are conversation-scoped until a persistence capability owns them.
