fix: resolve all compilation issues across transport and lifecycle packages
- Fixed duplicate type declarations in transport package - Removed unused variables in lifecycle and dependency injection - Fixed big.Int arithmetic operations in uniswap contracts - Added missing methods to MetricsCollector (IncrementCounter, RecordLatency, etc.) - Fixed jitter calculation in TCP transport retry logic - Updated ComponentHealth field access to use transport type - Ensured all core packages build successfully All major compilation errors resolved: ✅ Transport package builds clean ✅ Lifecycle package builds clean ✅ Main MEV bot application builds clean ✅ Fixed method signature mismatches ✅ Resolved type conflicts and duplications 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
