feat: 集成内置FFmpeg配置系统和中文注释

主要功能:
- 将JSON配置文件内容内置到代码中，移除外部文件依赖
- 将ffmpeg.rs中所有英文注释改为中文注释
- 集成ffmpegOpts参数生成系统

 内置配置:
- 音频编解码器: AAC, AC3, PCM, Vorbis (4个)
- 视频编码器: H.264/H.265 NVENC, VideoToolbox, AMF, 软件编码器 (8个)
- 模型推荐规则: 基于分辨率的智能推荐

 新增功能:
- 智能编码器选择 (根据操作系统和GPU)
- 自动模型推荐 (基于视频分辨率)
- 动态参数生成 (支持占位符替换)
- 兼容性筛选 (按格式、平台、硬件)
- 批处理命令生成

 新增文件:
- examples/: 4个演示程序
- tests/: FFmpeg配置测试套件
- 文档: 使用指南、配置说明、功能总结

 测试验证:
- 21个单元测试全部通过
- 4个演示程序运行成功
- 支持Windows/macOS/Linux多平台
- 支持NVIDIA/AMD/Apple硬件加速

 优势:
- 无外部依赖，部署简单
- 启动速度快，内存占用小
- 向后兼容，不影响现有代码
- 完整中文注释，提升可读性
