Add MCP server on both (systemd/launchd and docker)

[moarshy]

This PR adds a MCP server implementation for Naptha.

Whats been done

• Implemented a dedicated MCP server that uses the MCP SDK (node/mcp)
• launch and stop script modified with launching script for MCP
• Dockerfile for standalone MCP
• docker-compose file modified to start mcp

To test

• clone this branch
• copy .env.sample to .env (set it up)
• execute ./launch.sh
• test with the below script

import asyncio
from mcp import ClientSession
from mcp.client.sse import sse_client
import json


async def test_mcp_connection():
    print("Connecting to MCP server via SSE...")
    
    # Connect to the SSE endpoint - this is the proper way to connect
    # Do NOT use the /messages/ endpoint directly with HTTP POST

mcp not mpc. we will need to change all of these.
