* feat(frontend): pin the sent message to the top of the viewport After a send, keep the user's turn at the top of the viewport and let the streamed reply grow downward below the reading position, instead of the viewport chasing the bottom (ChatGPT-style send behavior). MessageList detects a freshly appended trailing human group while a run is active and hands its key to VirtualMessageList. The list then grows a flexible end spacer sized to the remaining viewport, so the last row can actually reach the top (the browser clamps the scroll without it), escapes the stick-to-bottom lock around the alignment, and re-escapes on a timeout chain until the resize animation from the optimistic message settles; the spacer shrinks as the reply grows and collapses when the run finishes. Scrolling down or the scroll-to-bottom button re-locks the follow. History pagination, thread switches and regenerates are excluded by construction and covered by DOM tests; Playwright covers the static and the virtualized list against a held run stream. * style(frontend): fix scroll-on-send test lint * fix(frontend): send-pin review follow-ups Review follow-ups on top of the send pin: - Hand scroll control back on the first genuine user input: the pin chain arms wheel/touchstart/pointerdown listeners on the scroller, and outline navigation plus the scroll-to-bottom button cancel it through cancelPinFollow — previously every tick reverted user scrolling for ~2s after a send. - Capture the mount-time tail key during the first render so the mount absorption is idempotent under StrictMode's double effect run. - Export LOCAL_HUMAN_MESSAGE_ID_PREFIX from core/threads/hooks and use it at both the mint site and the pin predicate. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>
