Restructure Project Architecture with Modular Routes and Configuration

- Refactored main application entry point to use centralized configuration
- Created modular route structure with separate files for different API endpoints
- Introduced app.config.ts for centralized environment variable management
- Moved tools and route logic into dedicated files
- Simplified index.ts and improved overall project organization
- Added comprehensive type definitions for tools and API interactions
