fix(results): avoid duplicate raw provider logs

[christso]

Summary

Provider-native raw streams are no longer duplicated into provider.log inside new run bundles. New eval artifacts keep the raw evidence in transcript-raw.jsonl and expose it through transcript_raw_path, while raw_provider_log_path remains a legacy/imported pointer for older or external bundles.

This keeps the artifact contract simpler without changing normalized transcript output or imported legacy bundle handling.
