Catches refactor drift across `.sh`, `Makefile` recursive calls, and
GitHub workflows. Includes fixes for the 5 bugs the new test surfaced
on first run: `make -C ROOT down`/`up` in the network stack refresh
helper (missed during the compose-* rename) and four
`make compose-deploymode=…` / `compose-deployapps=…` typos in
07/08/09_deploy_*.sh plus three docstring/echo references
(missing space after `compose-deploy`, introduced by the
deploy → compose-deploy sed-rename).
