- Replaced bitmap font (~195K drawbox commands) with drawtext (~2.2K)
- Write filter to temp file, use -/filter_complex to bypass ARG_MAX
- Added ffmpeg stderr logging for debugging
- Added FFMPEG Lazy static + ffmpeg_cmd() with DYLD_LIBRARY_PATH
- Replaced bitmap font rendering with drawtext (1 filter vs 35 per letter)
- Large traces (>1000 detections) may still fail (ARG_MAX with -vf)
