Bug Fix
"Готово/Done" footer disappears after page refresh — the completion indicator was only added dynamically during streaming (markDone()). After refreshing the page, messages loaded from history had no status footer.
Fix
_renderMsgAt() now adds the "Done" footer to the last assistant message in each conversation turn (before the next user message or end of chat), matching the live streaming behavior exactly.
