Add ffmpeg/x11grab-based video capture (libx264rgb, qp=0, true lossless
RGB) and an evdev-based keyboard state logger, orchestrated by a single
frame-tick loop so each JSONL input row lines up 1:1 with its video
frame. Unit-tested with fake keyboard/video components (no real device
or ffmpeg needed); real hardware capture still needs validation on the
recording PC.
