🤔 Possible Solution

1)The windows os doesnt handle all the icons in terminal and generates python char decoding errors
Fix: set PYTHONIOENCODING=utf-8
run this command in the terminal before running any of the python files in this package
Please add this to the documentation

2. npm dev commands fails which even though npm exists in windows
   Fix: this code in the run_system.py to handle npm.cmd shims

import shutils
self.logger.info(f"🔄 Starting {service_name} on port {config.port}...")

    try:
        # Setup environment
        env = os.environ.copy()
        if config.env:
            env.update(config.env)
        self.logger.info(f"Command: {' '.join(config.command)}")
                    # Resolve executable on Windows (handle npm -> npm.cmd shims)
        cmd = list(config.command)
        if os.name == 'nt' and cmd:
            resolved = shutil.which(cmd[0])
            if resolved:
                cmd[0] = resolved

        # Start process
        process = subprocess.Popen(
            cmd, #config.command,
            cwd=config.cwd,
            env=env,
            stdout=subprocess.PIPE,
            stderr=subprocess.STDOUT,
            text=True,
            bufsize=1,
            universal_newlines=True
        )

Start by reproducing the Windows behavior and run python system_health_check.py, then inspect run_system.py and the existing documentation. Compare the reported terminal decoding errors and npm command failures with the proposed Windows handling; done means the documented setup works and the affected commands run successfully on Windows.
