nevent and nprofile references come alive: nprofile mentions render as clickable @names beside their npub siblings, and note/nevent references become 'view note' links that fetch the event by id (relay hints first) and open its thread right in the app — the dim truncated stubs survive only for what genuinely can't resolve
