chore: remove configuration files and enhance blockchain explorer with advanced search, analytics, and export features

- Delete .aitbc.yaml.example CLI configuration template
- Delete .lycheeignore link checker exclusion rules
- Delete .nvmrc Node.js version specification
- Add advanced search panel with filters for address, amount range, transaction type, time range, and validator
- Add analytics dashboard with transaction volume, active addresses, and block time metrics
- Add Chart.js integration

+# CLI Directory Cleanup Plan
+
+## Current Issues Identified
+
+### **Files in Root Directory (Should be Organized)**
+- `client.py` - Client functionality (should be in examples or scripts)
+- `client_enhanced.py` - Enhanced client (should be in examples or scripts)
+- `gpu_test.py` - GPU testing (should be in tests/)
+- `miner_gpu_test.py` - GPU miner testing (should be in tests/)
+- `miner.py` - Miner functionality (should be in examples or scripts)
+- `test_exchange_e2e.py` - E2E test (should be in tests/)
+- `test_gpu_access.py` - GPU access test (should be in tests/)
+- `test_gpu_marketplace_bids.py` - GPU marketplace test (should be in tests/)
+- `test_ollama_blockchain.py` - Ollama blockchain test (should be in tests/)
+- `test_ollama_gpu_provider.py` - Ollama GPU provider test (should be in tests/)
+- `test_workflow.py` - Workflow test (should be in tests/)
+- `wallet.py` - Wallet functionality (should be in examples or scripts)
+
+### **Cleanup Strategy**
+
+#### **1. Create Proper Directory Structure**

+
+#### **2. File Categories**
+- **Examples**: Standalone scripts demonstrating CLI usage
+- **Tests**: All test files organized by type
+- **Scripts**: Utility scripts
+- **Documentation**: Documentation files
+- **Core**: Main CLI package (aitbc_cli/)
+
+#### **3. Benefits of Cleanup**
+- Better organization and maintainability
+- Clear separation of concerns
+- Easier to find specific functionality
+- Professional project structure
+- Easier testing and development
+
+## Execution Steps
+
+1. Create new directory structure
+2. Move files to appropriate directories
+3. Update any imports if needed
+4. Update documentation
+5. Verify everything works
