Replaced cp with symbolic link (ln -s) for better maintainability

Instead of copying the script file manually to ~/.local/bin using 'cp',
we now recommend creating a symbolic link with 'ln -s'.

This makes updates easier, as any changes pulled from the Git repository
are immediately reflected in the linked binary without needing to copy
the file again. It’s also safer in the long term, as users won’t
accidentally run outdated versions from ~/.local/bin.
