feat(video-from-script): 批量生产元数据增强 — 选题/转发文案/草稿命名/导出/草稿箱改名

- batch-pipeline.js: 新增 mark 元数据字段(topicA/B, draftName, forwardCopy, hashtags)
- batch-pipeline.js: 新增 export 命令导出 CSV/XLSX 最终表格
- batch-pipeline.js: 新增 rename-drafts 命令批量重命名剪映草稿(Mac 直接 mv 文件夹)
- batch-pipeline.js: 完善 displayTitle 向后兼容旧 topic 字段
- lib/phase-tts: 增强 TTS 生成稳定性
- lib/phase-videos: 视频生成优化
- lib/video-poll-utils: 提取轮询重试共享工具
- CLAUDE.md: 补充批量生产选题/转发文案/草稿命名/导出/草稿箱改名文档
- 执黑先行 account.json: 配置更新
