fix: Ensure backtest results save to DB and JSON files
- Remove duplicate DB save from quant.py (keep only in factor_runner) - Add explicit DB path creation with mkdir -p - Add JSON factor summaries to results/factors/ - Add debug logging for result structure - Fix logger.debug -> logger.info (RDAgentLog compatibility) - Update tests to match new architecture (240/240 passing) - Enhance extract_results.py with progress indicators
