chore(assets): 参赛提交规范红线修复（ASCII 化 + 相对路径）

按《参赛成果物提交规范·赛道一》§6 红线：
- samples/ 目录改名 sample/（git mv，保留历史）
- 10 个中日文样本文件 + docs 参赛手册 PDF 重命名为 ASCII
  （requirements_*/template_*/rules_*/contestant-handbook.pdf）
- tests/test_zh_template.py 硬编码绝对路径 D:\00_project\Genesis 改为相对路径
- 全局更新 21 个活动文件引用；历史日志/审查文档不改（追加说明记录）
全量 pytest 431 passed / 99.15%
