Ship the client Dockerfile with generated Nuxt apps; bump to v0.2.0

A generated monorepo's docker-compose.yml already built apps/client from
apps/client/Dockerfile, but the client overlay only embedded app/ and
public/, so the file never existed and `docker compose build client`
failed on every fresh project. The client-nuxt sync job now embeds the
template's Dockerfile too, and the Nuxt scaffold rewrites its pnpm pin to
the locally detected version - the one that produces the generated
project's lockfile - the same way it already stamps packageManager.

Bumps the submodule to the template commit that mounts ~/.npmrc as a
build secret for the registry token, and the Makefile VERSION to v0.2.0
for the release.
