refactor: extract script snippets to reusable scripts

- Create modular scripts for multi-node blockchain setup
- Extract 6 core setup scripts from workflow documentation
- Add master orchestrator script for complete setup
- Replace inline code with script references in workflow
- Create comprehensive README for script documentation
- Copy scripts to aitbc for cross-node execution
- Improve maintainability and reusability of setup process

Scripts created:
- 01_preflight_setup.sh - System preparation
- 02_genesis_authority_setup.sh - Genesis node setup
- 03_follower_node_setup.sh - Follower node setup
- 04_create_wallet.sh - Wallet creation
- 05_send_transaction.sh - Transaction sending
- 06_final_verification.sh - System verification
- setup_multinode_blockchain.sh - Master orchestrator

This makes the workflow cleaner and scripts reusable
while maintaining all functionality.

+# AITBC Multi-Node Blockchain Setup Scripts
+
+This directory contains modular scripts for setting up and managing a multi-node AITBC blockchain network.
+
+## Scripts Overview
+
+### Core Setup Scripts
+
+1. **01_preflight_setup.sh** - Pre-flight system preparation
+   - Stops existing services
+   - Updates systemd configurations
+   - Sets up environment files
+   - Installs CLI tool
+   - Creates keystore and directories
+
+2. **02_genesis_authority_setup.sh** - Genesis authority node setup (aitbc1)
+   - Pulls latest code
+   - Configures genesis authority
+   - Creates genesis block
+   - Starts blockchain services
+
+3. **03_follower_node_setup.sh** - Follower node setup (aitbc)
+   - Configures follower node
+   - Sets up cross-node communication
+   - Starts follower services
+
+4. **04_create_wallet.sh** - Wallet creation on follower node
+   - Creates new wallet using CLI tool
+   - Verifies wallet creation
+   - Returns wallet address
+
+5. **05_send_transaction.sh** - Transaction sending
+   - Sends AIT from genesis to wallet
+   - Monitors transaction confirmation
+   - Verifies balance update
+
+6. **06_final_verification.sh** - Complete system verification
+   - Checks blockchain synchronization
+   - Verifies transaction success
+   - Tests network health
+   - Validates service status
+
+### Master Script
+
+- **setup_multinode_blockchain.sh** - Master orchestrator script
+  - Runs all scripts in sequence
+  - Provides interactive execution
+  - Includes comprehensive summary
+  - Handles error checking
+
+## Usage
+
+### Individual Script Execution
+
+```bash
+# Run individual scripts
+./01_preflight_setup.sh
+./02_genesis_authority_setup.sh
+./03_follower_node_setup.sh
+./04_create_wallet.sh
+./05_send_transaction.sh
+./06_final_verification.sh
+```
+
+### Master Script Execution
+
+```bash
+# Run complete setup (interactive)
+./setup_multinode_blockchain.sh
+
+# Run complete setup (non-interactive)
+echo "y" | ./setup_multinode_blockchain.sh
+```
+
+## Script Dependencies
+
+### System Requirements
+- aitbc1 node (genesis authority)
+- aitbc node (follower)
+- SSH access between nodes
+- Redis service running
+- Python virtual environment
+
+### Environment Variables
+- `WALLET_ADDR` - Set by wallet creation script
+- `GENESIS_ADDR` - Set by genesis setup script
+
+### File Structure

+
+## Script Features
+
+### Error Handling
+- All scripts use `set -e` for error detection
+- Comprehensive error messages
+- Graceful failure handling
+
+### Logging
+- Clear step-by-step output
+- Progress indicators
+- Success/failure confirmation
+
+### Modularity
+- Each script is self-contained
+- Can be run independently
+- State management between scripts
+
+### Cross-Node Operations
+- Automatic SSH handling
+- Remote command execution
+- File synchronization
+
+## Customization
+
+### Environment Modifications
+- Edit `.env` files for different configurations
+- Modify service names as needed
+- Adjust network settings
+
+### Script Parameters
+- Wallet names can be changed
+- Transaction amounts are configurable
+- Network settings are customizable
+
+## Troubleshooting
+
+### Common Issues
+1. **SSH Connection**: Verify SSH keys between nodes
+2. **Service Failures**: Check systemd logs
+3. **Network Issues**: Verify Redis and RPC connectivity
+4. **Permission Errors**: Ensure proper file permissions
+
+### Debug Mode
+Add `set -x` to scripts for detailed execution tracing.
+
+### Log Locations
+- Systemd logs: `journalctl -u aitbc-blockchain-*`
+- Application logs: `/var/log/aitbc/`
+- Script logs: Console output
+
+## Security Considerations
+
+### Password Management
+- Keystore passwords stored in `/var/lib/aitbc/keystore/.password`
+- Change default password in production
+- Use proper key management
+
+### Network Security
+- SSH key authentication recommended
+- Firewall rules for RPC ports
+- Redis security configuration
+
+### File Permissions
+- Keystore files: `600` (owner only)
+- Scripts: `755` (executable)
+- Configuration: `644` (readable)
+
+## Maintenance
+
+### Regular Tasks
+- Monitor blockchain synchronization
+- Check service health
+- Update scripts as needed
+- Backup configurations
+
+### Updates
+- Pull latest code changes
+- Update script dependencies
+- Test script modifications
+- Document changes
+
+## Integration with Workflow
+
+These scripts are referenced in the main workflow documentation:
+- `/opt/aitbc/.windsurf/workflows/multi-node-blockchain-setup.md`
+
+The workflow now uses script references instead of inline code, making it:
+- More maintainable
+- Easier to test
+- Reusable components
+- Better organized
