Improve alias tests per CodeRabbit review

- Add verification that skipped packages don't appear in 'bun pm untrusted' output
- Add comment explaining that skipScriptsFrom accepts both alias and canonical names

This ensures the tests comprehensively verify that skipped packages are not
just excluded from the blocked count, but also from the untrusted dependencies
list entirely.
