Critical fixes for capture framerate:
1. write_all() now uses O_NONBLOCK — bridge never stalls on slow reader
2. FIFO pipe buffer increased to 64MB (~16 frames of 1080p UYVY)
3. Falls back to blocking mode after write completes
4. This prevents the card from dropping 95% of frames when ffmpeg can't keep up
