Pepijn 23c58f5f9e feat(streaming): decode diagnostic + fail benchmark on 0 frames ...

- benchmark: raise SystemExit if 0 frames were measured, so a run that produces no
  batches (swallowed decode error, all batches dropped) fails loudly instead of being
  reported green with NaN/zero numbers (the misleading "COMPLETED" CUDA jobs).
- add benchmarks/streaming/diagnose_decode.py: isolates the streaming decode path
  (resolve path -> fsspec.open -> torchcodec VideoDecoder -> get one frame) and prints
  package versions + the first bytes of the handle. Pinpoints decode failures: bad/
  placeholder bytes vs ffmpeg/torchcodec build issue. RoboCasa videos are AV1; the
  failure message calls out AV1 decoder + NVDEC-on-Ada requirements explicitly.
