将第102场及以后的派对场次迁移到2026每日派对干货目录
用法:
python3 scripts/migrate_2026_sections.py # 仅预览,不执行
python3 scripts/migrate_2026_sections.py --execute # 执行迁移
迁移规则:
- 从章节中筛选 section_title 包含第102场第103场... 的条目
- 按场次号排序依次赋 id 10.01, 10.02, 10.03, ...
- 更新 part_id=part-2026-daily, part_title=2026每日派对干货
- 更新 chapter_id=chapter-2026-daily, chapter_title=2026每日派对干货
依赖: pip install pymysql
