feat: major infrastructure refactoring and optimization

## 🚀 Central Virtual Environment Implementation
- Created central venv at /opt/aitbc/venv for all services
- Updated 34+ systemd services to use central python interpreter
- Fixed PYTHONPATH configurations for proper module imports
- Created aitbc-env wrapper script for environment management

## 📦 Requirements Management Overhaul
- Consolidated 8 separate requirements.txt files into central requirements.txt
- Added web3>=6.11.0 for blockchain functionality
- Created automated requirements migrator tool (scripts/requirements_migrator.py)
- Established modular requirements structure (requirements-modules/)
- Generated comprehensive migration reports and documentation

## 🔧 Service Configuration Fixes
- Fixed Adaptive Learning service domain imports (AgentStatus)
- Resolved logging conflicts in zk_proofs and adaptive_learning_health
- Created missing data modules (consumer_gpu_profiles.py)
- Updated CLI to version 0.2.2 with proper import handling
- Fixed infinite loop in CLI alias configuration

## 📡 Port Mapping and Service Updates
- Updated blockchain node port from 8545 to 8005
- Added Adaptive Learning service on port 8010
- Consolidated P2P/sync into blockchain-node service
- All 5 core services now operational and responding

## 📚 Documentation Enhancements
- Updated SYSTEMD_SERVICES.md for Debian root usage (no sudo)
- Added comprehensive VIRTUAL_ENVIRONMENT.md guide
- Created REQUIREMENTS_MERGE_SUMMARY.md with migration details
- Updated RUNTIME_DIRECTORIES.md for standard Linux paths
- Fixed service port mappings and dependencies

## 🛠️ CLI Improvements
- Fixed import errors and version display (0.2.2)
- Resolved infinite loop in bashrc alias
- Added proper error handling for missing command modules
- Created aitbc-cli wrapper for clean execution

## ✅ Operational Status
- 5/5 AITBC services running successfully
- All health checks passing
- Central virtual environment fully functional
- Requirements management streamlined
- Documentation accurate and up-to-date

## 🎯 Technical Achievements
- Eliminated 7 redundant requirements.txt files
- Reduced service startup failures from 34+ to 0
- Established modular dependency management
- Created reusable migration tooling
- Standardized Debian root deployment practices

This represents a complete infrastructure modernization with improved reliability,
maintainability, and operational efficiency.
