Thread showProgress through checkout and fix fetch progress flag

- Make checkout() and checkoutDetach() accept showProgress so callers
  can opt into --progress output; default remains --quiet
- Pass settings.showProgress to checkout() from git-source-provider
- Fix fetchOptions.showProgress not being set (was always undefined)
- Rebuild dist
