- Enhanced database schemas with comprehensive fields for swap and liquidity events
- Added factory address resolution, USD value calculations, and price impact tracking
- Created dedicated market data logger with file-based and database storage
- Fixed import cycles by moving shared types to pkg/marketdata package
