We don't want to introduce a new dependency, so we can use tsdown-migrate [...dirs], e.g., tsdown-migrate packages/*.

Is tinyglobby really necessary? I think shells like bash will also resolve glob patterns.

In my local, if I remove tinyglobby and rely directly on shell expansion like this, it would break support for PowerShell on Windows.

const baseCwd = process.cwd()
  const cwds =
    dirs && dirs.length > 0
      ? dirs.map((d) => path.resolve(baseCwd, d))
      : [baseCwd]
