feat: refactor event parsing architecture and add Raydium Launchpad support

Major changes:
- Refactor event parsing system: migrate scattered logs_* modules to unified event_parser architecture
- Add unified UnifiedEvent trait and EventParser trait for standardized event parsing interface
- Introduce GenericEventParser and EventParserFactory for plugin-style protocol extension
- Add match_event! macro to simplify event type matching and handling
- Add Raydium Launchpad (Bonk.fun) protocol support:
  - Complete buy/sell trading functionality
  - Pool state management and querying
  - Event parsing and subscription
- Update trading system to support new protocol architecture
- Refactor constants organization, rename raydium to raydium_launchpad
- Update documentation and example code

Technical improvements:
- Unified event interface design for better code maintainability
- Factory pattern implementation for dynamic protocol loading
- Generic event parser to reduce code duplication
- Improved error handling and type safety

Breaking Changes:
- Remove old logs_* modules, use new event_parser system
- Protocol constants path change: raydium -> raydium_launchpad
- Event subscription API updated to unified interface
