chronos-forecasting 1.4.1 의 의존성: `accelerate>=0.32,<1`.
기존 핀 `accelerate==0.30.1` 이 해당 범위 밖이라 pip 가
ResolutionImpossible 로 실패했음.

검증: python:3.11-slim 컨테이너에서
  pip install --dry-run -r reqs.txt (torch==2.3.1 포함, 30개 deps 전체)
exit 0. resolve 결과:
  chronos-forecasting 1.4.1
  transformers 4.41.2
  tokenizers 0.19.1
  accelerate 0.34.2
  torch 2.3.1
