Subject: [PATCH] run: refresh prompt layout after paste (#28164)

Pasting into the prompt textarea left its layout stale until the next edit, so the visible content did not reflect the pasted text. Mark the layout dirty on paste and notify the content-change handler once the renderer is idle so the prompt updates immediately.
