zikai 00e2a95fb7 Initial commit: audio2text 双语字幕生成服务
- 音频/视频转双语(英/中)SRT 字幕,Docker 容器化,CPU 开发/GPU 生产同一份代码
- faster-whisper ASR(词级时间戳) + 断句时间戳重算 + NLLB 翻译(模型不共驻)
- 分片上传(断点续传) + SQLite 持久化 + 主页/历史/日志页面
- 历史页文件名搜索;缓存定时清理(默认保留7天,可配置)
- 双 Dockerfile(cpu/gpu) + setup/start/stop 脚本

# audio2text — GPU 生产配置NVIDIA 3090 24G
# 模型按之前指定选型,质量优先:
# ASR = whisper large-v3-turbo8x 速度,质量接近 large-v3
# 翻译 = NLLB-200-distilled-1.3B(质量最好)
# ASR 与翻译不共驻:翻译时卸载 Whisper 独占显存跑大 batch。
