- Replace instance-based EventParser with static method design
- Introduce ParserCache module for protocol config caching
- Simplify EventProcessor to pure functional handlers
- Optimize metrics: remove min/max tracking, keep last + avg only
- Reduce atomic operations in hot path for better performance
- Convert UnifiedEvent from trait object (Box<dyn UnifiedEvent>) to concrete enum type
- Remove match_event! macro in favor of native match expressions
- Simplify event metadata access: event.event_type() -> event.metadata().event_type
- Unify event callback signatures: Fn(Box<dyn UnifiedEvent>) -> Fn(UnifiedEvent)
- Update all example code to use the new enum-based event system
- Optimize type system to reduce runtime overhead and improve type safety
Affected scope:
- Core event parser and processor
- All protocol event definitions (PumpFun, PumpSwap, Bonk, Raydium series, etc.)
- gRPC and Shred streaming modules
- All example code
modernize dependencies
- Upgrade all Solana SDK dependencies
from v2.3.x to v3.0.0

new gRPC and protobuf versions
- Regenerate proto files with updated
codegen and server implementations
- Introduce EventSource enum (Grpc, Shred) for better event source management
- Refactor start_block_processing_thread to conditionally spawn threads based on source type

- Enhance parse_token_account_event to automatically detect and parse Mint accounts
- Update all example code to use new event types and structures
- Improve event type semantics for better developer experience
- feat(examples): add nonce_listen_example for nonce account tracking
- feat(examples): add token_balance_listen_example for balance monitoring
- feat(parser): implement NonceAccountEvent with nonce state parsing
