- ✅ Detailed opportunity logging with full transaction parsing
- ✅ Professional log formatting with timestamps and level indicators
- ✅ Log level filtering (DEBUG shows all, INFO filters out debug messages)
## Enhanced Logger Features:
- Custom timestamp format: `2025/09/14 06:53:59 [LEVEL] message`
- Proper log level hierarchy and filtering
- Special OPPORTUNITY level that always logs regardless of config
- Detailed opportunity logs with tree structure showing:
- Transaction hash, from/to addresses
- Method name and protocol (UniswapV2/V3)
- Amount In/Out/Min values in human-readable format
- Estimated profit (placeholder for future price oracle)
- Additional structured data (tokens, fees, deadlines, etc.)
## L2 Parser Enhancements:
- New SwapDetails struct for structured swap data
- Enhanced DEX function parameter decoding
- Support for UniswapV2 and V3 function signatures
