[feat] baseline system - auto-generates baselines before experiments

- Added _extract_baseline_content() to extract output from create_file tool calls
- Baselines now saved to logs/{model}/{scenario}/baseline.md
- Added global oversight fallback (scenario-specific → global oversight dir)
- Updated config_loader with oversight level loading from scenario dirs
