Devin AI f9dcec7369 fix(infra): restore canonical_json_bytes non-ASCII behavior and dataset_ingest list safety
- canonical_json_bytes now delegates to canonical_json (ensure_ascii=False)
  matching the original per-file implementations in emitter and loopback
- dataset_ingest_rds.py restores isinstance(data, list) safety check from
  original load_jsonl, wrapping lib.jsonl.load_json
