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
