perf: implement SIMD-accelerated event processing and optimize streaming performance
- Add SIMD utilities for fast byte array comparison and discriminator matching - Optimize event processor with batch processing and memory pool - Refactor global state management with concurrent data structures - Remove deprecated batch processing module - Enhance metrics collection with reduced overhead - Improve parser efficiency across all protocol implementations - Add performance benchmarking dependencies (criterion, wide) - Update documentation and examples for new architecture Performance improvements: - SIMD-accelerated byte operations for instruction parsing - Concurrent HashMap (DashMap) for better multi-threading - Optimized memory allocation patterns - Reduced lock contention in event processing pipeline Breaking changes: Removed batch.rs module, updated parser interfaces
