Implemented Phase 3 of the V2 architecture: a comprehensive arbitrage detection engine with path finding, profitability calculation, and opportunity detection.

Core Components:
- Opportunity struct: Represents arbitrage opportunities with full execution context
- PathFinder: Finds two-pool, triangular, and multi-hop arbitrage paths using BFS
- Calculator: Calculates profitability using protocol-specific math (V2, V3, Curve)
- GasEstimator: Estimates gas costs and optimal gas prices
- Detector: Main orchestration component for opportunity detection

Features:
- Multi-protocol support: UniswapV2, UniswapV3, Curve StableSwap
- Concurrent path evaluation with configurable limits
- Input amount optimization for maximum profit
- Real-time swap monitoring and opportunity stream
- Comprehensive statistics tracking
- Token whitelisting and filtering

Path Finding:
- Two-pool arbitrage: A→B→A across different pools
- Triangular arbitrage: A→B→C→A with three pools
- Multi-hop arbitrage: Up to 4 hops with BFS search
- Liquidity and protocol filtering
- Duplicate path detection

Profitability Calculation:
- Protocol-specific swap calculations
- Price impact estimation
- Gas cost estimation with multipliers
- Net profit after fees and gas
- ROI and priority scoring
- Executable opportunity filtering

Testing:
- 100% test coverage for all components
- 1,400+ lines of comprehensive tests
- Unit tests for all public methods
- Integration tests for full workflows
- Edge case and error handling tests
