'New version found. Refresh to update' toast

Editor assessment

`feat: 'New version found. Refresh to update' toast` quotes the exact UI copy, which is maximal specificity for a toast addition; the reader knows the trigger context and the message verbatim. Feat correctly marks new functionality, and no scope is needed. No body explains when the toast fires or the update mechanism behind it — a modest gap — but the subject is self-sufficient. Quoting is a permitted stylistic choice. Imperative-equivalent noun phrase, no period, compact. Clear, correct, publishable.
