Subject: [PATCH] Abort setup when create-vue is interrupted or cancelled

create-vue exits 0 when its prompts are cancelled, so a zero return code
is not proof of success: also require frontend/package.json to exist, and
treat Ctrl-C (KeyboardInterrupt) as failure instead of a traceback. The
caller already exits 1 on failure, so the setup no longer continues with
a missing or partial frontend.
