Subject: [PATCH 1/2] test: run apply.sh once per detected stack against a
 throwaway fixture

demo/scaffold.sh's fixture is node-only, so no fixture had ever run
apply.sh's fill()/command tables against any other stack -- exactly how
a real, shipped-since-v1.0.0 crash on every Go repo went unnoticed
until it was reported and fixed separately.

Adds a smoke_stack loop covering all 11 detected stacks plus generic:
writes a bare marker file, runs apply.sh against it with a throwaway
config, and asserts a clean exit. Fixes #42.
