refactor: overhaul event parser architecture for better performance

Browse Source 
- 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
