## Changes Made
This PR adds the following changes:
- Added a new example demonstrating LangGraph integration with Solana
Agent Kit
- Implemented a multi-agent system with specialized agents for different
tasks
- Added state management and routing logic using LangGraph's StateGraph
- Integrated Tavily search capabilities for enhanced general-purpose
queries
- Added support for token swaps using Jupiter DEX
- Implemented TypeScript-based project structure with full type safety
- Added comprehensive documentation and architecture diagram
## Implementation Details
- Created a directed workflow using StateGraph with the following
components:
- Manager Agent: Handles query classification and routing
- General Agent: Processes basic queries with Tavily search integration
- Transfer/Swap Agent: Handles token transfers and DEX operations
- Read Agent: Manages blockchain data queries
- Implemented state management using LangGraph annotations for query
classification
- Added environment-based configuration for API keys and RPC endpoints
- Integrated with external dependencies:
- @langchain/community v0.3.20
- @langchain/core v0.3.26
- @langchain/langgraph v0.2.36
- solana-agent-kit v1.3.0
- Set up TypeScript configuration with ESM support

## Additional Notes
- The implementation follows a modular architecture as shown in the
architecture diagram
- Supports both read and write operations on the Solana blockchain
- Includes comprehensive error handling and type safety
- Provides flexible configuration through environment variables
- Project structure follows best practices with clear separation of
concerns
- Includes example queries for testing different agent pathways
## Checklist
