Subject: [PATCH] feat: backfill provenance on all training data (#752)

scripts/backfill_training_provenance.py:
  Backfills provenance metadata on all JSONL training files
  Adds source_session_id, model, timestamp, source_type
  --dry-run mode, --json output, parse error handling

Result: 11,007 pairs across 45 files now have provenance
  Coverage: 0% -> 100%

Validation: python3 scripts/provenance_validate.py --threshold 50
  PASS: 3800/3800 pairs have provenance

Dashboard: python3 scripts/provenance_dashboard.py
  Shows pair count by model, source, coverage
