Subject: [PATCH] fix: prevent yarn 2+ error in `assets:precompile` (#241)

Yarn's migration guide mentions that selecting which dependencies are installed (dev or prod) requires the
workspace-tools plugin.

It's now the user's responsibility to ensure any build dependencies are available when vite build is run.
