refactor: remove duplicate node setup template and empty templates directory

Node Setup Template Cleanup - Complete:
✅ DUPLICATE TEMPLATE REMOVED: Cleaned up redundant node setup template
- templates/node_setup_template.sh: Removed (duplicate of existing functionality)
- templates/ directory: Removed (empty after cleanup)
- Root cause: Template was outdated and less functional than working scripts

✅ DUPLICATION ANALYSIS COMPLETED:
📋 templates/node_setup_template.sh: Basic 45-line template with limited functionality
📁 scripts/deployment/provision_node.sh: Working 33-line node provisioning script
📁 scripts/workflow/03_follower_node_setup.sh: Advanced 58-line follower setup
📁 scripts/workflow-openclaw/03_follower_node_setup_openclaw.sh: Comprehensive 214-line OpenClaw setup

✅ WORKING SCRIPTS PRESERVED:
🔧 scripts/deployment/provision_node.sh: Node provisioning with basic functionality
🔧 scripts/workflow/03_follower_node_setup.sh: Advanced follower node setup
🔧 scripts/workflow-openclaw/03_follower_node_setup_openclaw.sh: OpenClaw agent-based setup
📖 Documentation: References to genesis templates (different concept) preserved

✅ TEMPLATE FUNCTIONALITY ANALYSIS:
❌ Removed: Basic git clone, venv setup, generic configuration
✅ Preserved: Advanced follower-specific configuration, OpenClaw integration
✅ Preserved: Better error handling, existing venv usage, sophisticated setup
✅ Preserved: Multi-node coordination and agent-based deployment

✅ CLEANUP BENEFITS:
✅ No Duplication: Single source of truth for node setup
✅ Better Functionality: Preserved more advanced and working scripts
✅ Cleaner Structure: Removed empty templates directory
✅ Clear Choices: Developers use working scripts instead of outdated template

✅ PRESERVED DOCUMENTATION REFERENCES:
📚 docs/beginner/02_project/2_roadmap.md: References to config templates (different concept)
📚 docs/expert/01_issues/09_multichain_cli_tool_implementation.md: Genesis block templates
🎯 Context: These are configuration templates, not node setup templates
📝 Impact: No functional impact on documentation

RESULT: Successfully removed duplicate node setup template and empty templates directory while preserving all working node setup scripts and documentation references to different template concepts.
