Error when two packages have same prefix

[utkarshk384]

The issue here is that I have two packages named as @UI/theme and @UI/theme-utils and when I try to use any scripts with @UI/theme the following error is thrown to me:

☔️ error an identifier must only match a single package but "theme" matches the following packages: 
☔️ error @UI/theme
☔️ error @UI/theme-utils

Upon looking at the source code I found the following lines of code that could possibly be causing the issue: https://github.com/Thinkmill/manypkg/blob/0fecbcb94df338ed1a494c94e30fcacbed2fab5c/packages/cli/src/run.ts#L25-L30

This code snippet lies within the runCmd function here.

I suppose that arg[0] might be the package that is calling the CLI command. So, for example, I am currently calling the CLI command for the theme package therefore arg[0] should be @UI/theme.

With that out of the way now I think includes is matching all the packages that have that same name, therefore, causing the issue here. I'll try to make a pull request to fix the issue.

Edit: args[0] doesn't equal to @UI/theme but just theme. I had overlooked some parts of the code
