refactor: comprehensive scripts directory reorganization by functionality

Scripts Directory Reorganization - Complete:
✅ FUNCTIONAL ORGANIZATION: Scripts sorted into 8 logical categories
- github/: GitHub and Git operations (6 files)
- sync/: Synchronization and data replication (4 files)
- security/: Security and audit operations (2 files)
- monitoring/: System and service monitoring (6 files)
- maintenance/: System maintenance and cleanup (4 files)
- deployment/: Deployment and provisioning (11 files)
- testing/: Testing and quality assurance (13 files)
- utils/: Utility scripts and helpers (47 files)

✅ ROOT DIRECTORY CLEANED: Only README.md remains in scripts root
- scripts/README.md: Main documentation
- scripts/SCRIPTS_ORGANIZATION.md: Complete organization guide
- All functional scripts moved to appropriate subdirectories

✅ SCRIPTS CATEGORIZATION:
📁 GitHub Operations: PR resolution, repository management, Git workflows
📁 Synchronization: Bulk sync, fast sync, sync detection, SystemD sync
📁 Security: Security audits, monitoring, vulnerability scanning
📁 Monitoring: Health checks, log monitoring, network monitoring, production monitoring
📁 Maintenance: Cleanup operations, performance tuning, weekly maintenance
📁 Deployment: Release building, node provisioning, DAO deployment, production deployment
📁 Testing: E2E testing, workflow testing, QA cycles, service testing
📁 Utilities: System management, setup scripts, helpers, tools

✅ ORGANIZATION BENEFITS:
- Better Navigation: Scripts grouped by functionality
- Easier Maintenance: Related scripts grouped together
- Scalable Structure: Easy to add new scripts to appropriate categories
- Clear Documentation: Comprehensive organization guide with descriptions
- Improved Workflow: Quick access to relevant scripts by category

✅ DOCUMENTATION ENHANCED:
- SCRIPTS_ORGANIZATION.md: Complete directory structure and usage guide
- Quick Reference: Common script usage examples
- Script Descriptions: Purpose and functionality for each script
- Maintenance Guidelines: How to keep organization current
