Run ncc via npm run build-dist

This adds a convenience `script` entry to the `package.json` file that
allows bundling everything into `dist/`, dependency-free.

Since `ncc` generates a lot of `.d.ts` files (which are not required to
run the GitHub Action), we go ahead and tell Git to ignore these.
