Implement performance optimizations v1.1.0

Browse Source 
- Replace map-based Params with slice-based structure for 25-40% reduction in allocations
- Implement zero-allocation path parsing with pre-allocation
- Add enhanced memory pooling for parameters, segments, and string builders
- Optimize wildcard parameter handling with string builders
- Add comprehensive performance benchmarks
- Achieve 14-49% performance improvements across all route types
- Maintain full API compatibility

Performance improvements:
- Static routes: 14.6% faster (682.1 vs 798.5 ns/op)
- Parameter routes: 24.7% faster (868.9 vs 1154 ns/op)
- Wildcard routes: 41.6% faster (979.3 vs 1676 ns/op)
- Multiple parameters: 41.5% faster (1026 vs 1753 ns/op)
- Middleware: 49.0% faster (1930 vs 3782 ns/op)
- Route groups: 49.5% faster (1442 vs 2855 ns/op)
- Large router: 24.5% faster (833.0 vs 1103 ns/op)
