fix(parsing): implement enhanced parser integration to resolve zero address corruption

Browse Source 
Comprehensive architectural fix integrating proven L2 parser token extraction
methods into the event parsing pipeline through clean dependency injection.

Core Components:
- TokenExtractor interface (pkg/interfaces/token_extractor.go)
- Enhanced ArbitrumL2Parser with multicall parsing
- Modified EventParser with TokenExtractor injection
- Pipeline integration via SetEnhancedEventParser()
- Monitor integration at correct execution path (line 138-160)

Testing:
- Created test/enhanced_parser_integration_test.go
- All architecture tests passing
- Interface implementation verified

Expected Impact:
- 100% elimination of zero address corruption
- Successful MEV detection from multicall transactions
- Significant increase in arbitrage opportunities
