Add comprehensive unit tests for all execution engine components:

Component Test Coverage:
- UniswapV2 encoder: 15 test cases + benchmarks
- UniswapV3 encoder: 20 test cases + benchmarks
- Curve encoder: 16 test cases + benchmarks
- Flashloan manager: 18 test cases + benchmarks
- Transaction builder: 15 test cases + benchmarks
- Risk manager: 25 test cases + benchmarks
- Executor: 20 test cases + benchmarks

Test Categories:
- Happy path scenarios
- Error handling and edge cases
- Zero/invalid inputs
- Boundary conditions (max amounts, limits)
- Concurrent operations (nonce management)
- Configuration validation
- State management

Key Test Features:
- Protocol-specific encoding validation
- ABI encoding correctness
- Gas calculation accuracy
- Slippage calculation
- Nonce management thread safety
- Circuit breaker behavior
- Risk assessment rules
- Transaction lifecycle

Total: 129 test cases + performance benchmarks
Target: 100% test coverage for execution engine

Related to Phase 4 (Execution Engine) implementation.
