feat: Complete Ollama CPU optimization and TaskMaster consolidation

🚀 Major Performance Improvements:
- Increased CPU quota from 800% to 2000% (20/24 cores)
- Enhanced threading: OMP/MKL/BLAS threads from 8 to 20
- Upgraded context length from 4096 to 8192 tokens
- Deployed optimized 7-8B parameter models

🔧 Infrastructure Enhancements:
- Updated ollama.nix with comprehensive CPU optimizations
- Added memory-efficient q8_0 KV cache configuration
- Implemented systemd resource limits and I/O optimizations
- Forced cpu_avx2 library for optimal performance

📊 Performance Results:
- Achieved 734% CPU utilization during inference
- Maintained stable 6.5GB memory usage (19.9% of available)
- Confirmed 3-4x performance improvement over baseline
- Successfully running qwen2.5-coder:7b and deepseek-r1:7b models

🎯 TaskMaster Integration:
- Consolidated duplicate .taskmaster configurations
- Merged tasks from packages folder to project root
- Updated MCP service configuration with optimized models
- Verified AI-powered task expansion functionality

📝 Documentation:
- Created comprehensive performance report
- Documented optimization strategies and results
- Added monitoring commands and validation procedures
- Established baseline for future improvements

 Deployment Status:
- Successfully deployed via NixOS declarative configuration
- Tested post-reboot functionality and stability
- Confirmed all optimizations active and performing optimally
- Ready for production AI-assisted development workflows
