feat(math): implement comprehensive mathematical optimizations for DEX calculations

- Add new math package with optimized implementations for major DEX protocols
- Implement Uniswap V2, V3, V4, Curve, Kyber, Balancer, and Algebra mathematical functions
- Optimize Uniswap V3 pricing functions with caching and uint256 optimizations
- Add lookup table optimizations for frequently used calculations
- Implement price impact and slippage calculation functions
- Add comprehensive benchmarks showing 12-24% performance improvements
- Fix test expectations to use correct mathematical formulas
- Document mathematical optimization strategies and results
