Currently baselines are persisted via CI artifact upload/download. Direct S3/GCS support simplifies setup for teams where CI artifacts are ephemeral or cross-workflow sharing is needed.
Acceptance criteria
baseline: s3://bucket/path/baseline.json in config- Support S3 and GCS backends
- Auth via standard cloud SDK credential chains (env vars, instance metadata)
buildgraph generate --upload and buildgraph analyze --download flags
