写匠 · 按内容批量拟标题

Use when a 写匠 (aiwriter) user wants titles for many cards at once - e.g. imported notes whose titles are code strings like 20230915103322-a8f3c1 or uuids. Lists the cards, extracts titles from the author's own sentences, shows a preview, and renames only after the author approves; every run leaves an undo record. Triggers: 批量拟标题、批量改标题、卡片标题是一串代码、 按内容起标题、导入的卡片没有标题。
