refactor: overhaul event parser architecture for better performance
- Centralize event parsing logic and remove factory pattern - Add high-performance clock module to reduce latency - Consolidate protocol parsers with unified interface - Introduce account pubkey caching and streamline traits - Remove deprecated macro-based and multi-protocol implementations
