feat: add command line arguments support for os.Args in kernel

[sumansaurabh]

Summary

Implemented command line arguments support for os.Args in the kernel to complement the existing environment variables functionality.

Changes

• Added command line argument parsing capability to the kernel
• Integrated with existing -append parameter mechanism used for environment variables
• Populated os.Args with parsed command line arguments
• Maintained backward compatibility with current environment variable handling

Why

This enhancement allows developers to pass command line arguments to kernel programs using the same -append parameter that currently supports environment variables, providing a more complete runtime environment for kernel applications.

Fixes #70
