Add npm script to regenerate the package-lock.json (#66)

Adds a new npm script called `regen-package-lock` to the root
`package.json`. This script removes all `node_modules` and
`package-lock.json` files from the root and all workspaces, then
reinstalls dependencies and runs `npm audit:fix` to ensure a clean and
secure dependency tree.
