Bug1：视频完全无声

根因：_mux_video_with_audio() 已实现但从未被调用，Step 8 直接 shutil.copy2 复制无声视频返回。

修复：将 shutil.copy2(str(final_video), str(output_path)) 替换为 _mux_video_with_audio(final_video, audio_path, output_path)，使用原始驱动音频封装。

Bug2：嘴巴区域紫色/灰色色块

根因：GFPGAN 在 FP16 模式下色偏 + face parsing mask 边缘不精准。

修复：

  1. GFPGAN 加载时不再使用 FP16，强制 FP32 推理
  2. 推理时 input tensor 也保持 FP32
  3. 增强后增加色彩校正（均值/标准差对齐到原始人脸区域）
  4. weight 从 0.5 调低至 0.35，减少增强覆盖比例

Bug1 无声：
- Step 8 将 shutil.copy2 替换为 _mux_video_with_audio
- 推理输出的无声视频现在会正确封装驱动音频

Bug2 紫色/灰色色块：
- GFPGAN 模型加载和推理均改用 FP32，消除 FP16 色偏
- 增强后增加色彩校正（均值/标准差对齐到原始人脸）
- weight 从 0.5 降至 0.35，减少增强覆盖比例
- 保留归一化逻辑 [-1, 1] 确保模型输入正确
