PipeWire capture keeps its size and last frame after its stream stops, so the recorder follows the stream state OBS logs. Recording fails when the segment on disk stops growing (OBS kept counting bytes into a dead muxer and missed a full disk) and stops while enough space remains to finalise the last segment. Failures stay visible after the output stops. Adds a check command that verifies keyframe-aligned segments and a remux across segment boundaries, and gives the rig desktop audio.
