feat(pipeline): detect node crashes and tally dropped frames

Browse Source

Register a KPN event handler in both scene_analyze and scene_preview:
  - Overflow events accumulate per-node dropped-frame counts, printed on exit.
  - A Closed event from any node other than result_sink at EOF means a stage
    died; trip an atomic so the main loop bails out instead of hanging on
    'done' forever, and exit non-zero.

Bumps external/KPN to the commit that exposes set_event_handler / NodeEvent.
