`vp run` does not preserve shell semantics for package.json scripts

[TheAlexLichter]

vp run currently executes package.json scripts without fully preserving the shell semantics provided by package managers. For example, given:

{
  "scripts": {
    "lint": "vp lint packages/*/src"
  }
}

pnpm lint expands packages/*/src, while vp run lint passes it literally and fails with "No files found to lint."
