fix(integration): resolve test failures and package dependencies
- Fixed duplicate package declarations in arbitrum parser - Resolved missing methods in events parser (ParseTransaction, AddKnownPool) - Fixed logger test assertion failures by updating expected log format - Updated NewPipeline constructor calls to include ethClient parameter - Fixed nil pointer dereference in pipeline processing - Corrected known pool mappings for protocol identification - Removed duplicate entries in parser initialization - Added proper error handling and validation in parsers These changes resolve the build failures and integration test crashes that were preventing proper testing of the MEV bot functionality.
