feat(ui): 强化 AI 工作中动效——构思占位/流式进度条/波动三点/转圈

- 动效基元:ai-dot 波动(三点竖跳)、ai-stream 不确定进度条、ai-breathe 呼吸微光(均带 reduced-motion 回退)
- ThinkingIndicator 升级为明显波动;新增 Spinner / StreamingBar / GenerationSkeleton 原子件;Button 加 loading 态
- 写作台:首 token 前正文区『AI 正在构思本章…』占位(补最大缺口,不再空白像卡死)+ 流式顶部进度条
- 整章重写流式进度条;续写/润色忙碌骨架 + 触发键转圈;生成器/角色/世界观改用 Button loading
