🔧 Fix: Complete compilation and functionality fixes for AMCP Core v1.5.0

📋 Summary

This pull request resolves all compilation issues and adds comprehensive CLI and demo functionality to AMCP Core v1.5.0. All classes now compile cleanly, tests pass, and the framework includes a fully functional command-line interface with interactive demos.

🎯 Issues Fixed

Compilation Issues Resolved:

✅ EventPriority visibility: Made enum public and moved to separate file
✅ Missing Event methods: Added getSource(), getTarget(), source(), target()
✅ Agent method visibility: Made publish() method public for external access
✅ Event handling: Added handleEvent() and onEventReceived() methods
✅ AgentContext interface: Fixed method signatures and implementations

New Features Added:

✅ CLI Interface: Complete command-line tool with version/help/demo commands
✅ Interactive Demo: Full agent simulation with event communication
✅ Standalone JAR: Self-contained executable with all dependencies
✅ Comprehensive Testing: Automated test suite verifying all functionality

🚀 New Functionality

1. Command-Line Interface (AMCPCli)

public class AMCPCli {
    // Provides version, help, and demo commands
    // Configured as main class in JAR manifest
}

2. Interactive Demo (AMCPDemo)

public class AMCPDemo {
    // Complete agent simulation environment
    // Interactive CLI for creating agents and sending events
    // Real-time event logging and agent status monitoring
}

3. Enhanced Agent Framework

public abstract class Agent {
    // Public publish() method for external access
    // Event handling with onEventReceived() callback
    // Proper lifecycle management with error handling
}

4. Improved Event System

public final class Event {
    // getSource() and getTarget() convenience methods
    // Builder pattern with source() and target() methods
    // Comprehensive metadata and priority support
}

📦 Build Configuration

Maven Plugins Added:

JAR Plugin: Configures main class for executable JARs
Shade Plugin: Creates standalone JAR with all dependencies
Javadoc Plugin: Generates comprehensive API documentation

Manifest Configuration:

<manifest>
    <mainClass>org.amcp.cli.AMCPCli</mainClass>
    <addClasspath>true</addClasspath>
</manifest>

🎮 Usage Examples

CLI Commands:

# Show version
java -jar amcp-core-1.5.0-standalone.jar version

# Run interactive demo
java -jar amcp-core-1.5.0-standalone.jar demo

# Show help
java -jar amcp-core-1.5.0-standalone.jar help

Interactive Demo Features:

Create and manage multiple agents
Send events between agents with custom topics and payloads
Real-time event logging and agent status monitoring
Broadcast and targeted messaging
Agent lifecycle management (activate/deactivate)

Programmatic Usage:

// Create and activate an agent
Agent myAgent = new MyAgent("agent-001", "MyAgentType");
myAgent.activate();

// Create and publish an event
Event event = Event.builder()
    .topic("my.topic")
    .payload("Hello AMCP!")
    .priority(EventPriority.NORMAL)
    .build();
    
myAgent.publish(event);
