feat: add NVENC hardware encoding support for FFmpeg

Browse source 
Add FFMPEG_PREFER_HARDWARE env var to enable hardware acceleration
Use h264_nvenc and hevc_nvenc encoders when hardware preferred
Fall back to software encoders (libx264/libx265) when disabled
Add comprehensive tests for hardware/software encoding modes
Update README with new environment variable documentation
This enables GPU-accelerated video encoding for better performance on systems with NVIDIA GPUs.
