项目整理：重写主文档、归档过时文档、清理死代码、新增音频制作手册

文档整理:
- 重写 game/操作说明.md 为项目主文档（6游戏/6手势/旁白/模型生成音频/TTS两步流程）
- 归档过时文档至 other_docs/（林夏原始设计、旧执行文档）
- 新增 docs/音频制作执行手册.md（从零制作游戏音频的完整流程）
- docs/ 下保留旁白音色提示词、音频脚本

代码清理:
- 删除旧架构死代码: story.js / gestures.js / profile.js
- 删除耦合旧架构的过时测试目录 game/tests/

脚本配置修正:
- check_tts_env.sh: 启动脚本路径 AutoVideo → tts-server（实际位置）
- gen_narrator_samples.py: 硬编码地址改为环境变量，默认对齐 tts-server 端口 8000
