d0973b2adf Phase 3: Implement Core Task Execution Engine (v0.4.0) 
This commit implements Phase 3 of the CHORUS task execution engine development plan,
replacing the mock implementation with a real AI-powered task execution system.

## Major Components Added:

### TaskExecutionEngine (pkg/execution/engine.go)
- Complete AI-powered task execution orchestration
- Bridges AI providers (Phase 1) with execution sandboxes (Phase 2)
- Configurable execution strategies and resource management
- Comprehensive task result processing and artifact handling
- Real-time metrics and monitoring integration

### Task Coordinator Integration (coordinator/task_coordinator.go)
- Replaced mock time.Sleep(10s) implementation with real AI execution
- Added initializeExecutionEngine() method for setup
- Integrated AI-powered execution with fallback to mock when needed
- Enhanced task result processing with execution metadata
- Improved task type detection and context building

### Key Features:
- **AI-Powered Execution**: Tasks are now processed by AI providers with appropriate role-based routing
- **Sandbox Integration**: Commands generated by AI are executed in secure Docker containers
- **Artifact Management**: Files and outputs generated during execution are properly captured
- **Performance Monitoring**: Detailed metrics tracking AI response time, sandbox execution time, and resource usage
- **Fallback Resilience**: Graceful fallback to mock execution when AI/sandbox systems are unavailable
- **Comprehensive Error Handling**: Proper error handling and logging throughout the execution pipeline

### Technical Implementation:
- Task execution requests are converted to AI prompts with contextual information
- AI responses are parsed to extract executable commands and file artifacts
- Commands are executed in isolated Docker containers with resource limits
- Results are aggregated with execution metrics and returned to the coordinator
- Full integration maintains backward compatibility while adding real execution capability

This completes the core execution engine and enables CHORUS agents to perform real AI-powered task execution
instead of simulated work, representing a major milestone in the autonomous agent capability.

0dbb6bb588 Implement Phase 1: CHORUS Human Agent Portal (HAP) Multi-Binary Architecture 
This commit completes Phase 1 of the HAP implementation by restructuring CHORUS
from a single binary to a dual-binary architecture that supports both autonomous
agents and human agent portals using shared P2P infrastructure.

## Key Changes

### Multi-Binary Architecture
- **cmd/agent/main.go**: Autonomous agent binary (preserves all original functionality)
- **cmd/hap/main.go**: Human Agent Portal binary (Phase 2 stub implementation)
- **cmd/chorus/main.go**: Backward compatibility wrapper with deprecation notices

### Shared Runtime Infrastructure
- **internal/runtime/shared.go**: Extracted all P2P infrastructure initialization
- **internal/runtime/agent_support.go**: Agent-specific behaviors and health monitoring
- Preserves 100% of existing CHORUS functionality in shared components

### Enhanced Build System
- **Makefile**: Complete multi-binary build system
  - `make build` - Builds all binaries (agent, hap, compatibility wrapper)
  - `make build-agent` - Agent only
  - `make build-hap` - HAP only
  - `make test-compile` - Compilation verification

## Architecture Achievement

✅ **Shared P2P Infrastructure**: Both binaries use identical libp2p, DHT, HMMM, UCXL systems
✅ **Protocol Compatibility**: Human agents appear as valid peers to autonomous agents
✅ **Container-First Design**: Maintains CHORUS's container deployment model
✅ **Zero Functionality Loss**: Existing users see no disruption

## Phase 1 Success Metrics - ALL ACHIEVED

✅ `make build` produces `chorus-agent`, `chorus-hap`, and `chorus` binaries
✅ Existing autonomous agent functionality unchanged
✅ Both new binaries can join same P2P mesh
✅ Clean deprecation path for existing users

## Next Steps

Phase 2 will implement the interactive terminal interface for chorus-hap, enabling:
- HMMM message composition helpers
- UCXL context browsing
- Human-friendly command interface
- Collaborative decision participation
