ci / build-test (push) Successful in 1m28s
The updater was emitted from a heredoc inside the installer, so a container provisioned before it existed had no way to obtain /usr/bin/update — 'update' just reported command not found, with no path forward short of reinstalling. Ship it as deploy/install/metervault-update.sh and have the installer install(1) it from the checkout it just built. An already-provisioned container can now bootstrap from its own source tree after a git pull, and the updater refreshes itself (atomic rename, since bash reads a running script lazily) so the same stranding does not recur. Uses echo rather than msg_warn for the missing-file case: msg_warn is not otherwise relied on in this script, and an undefined function under the framework ERR trap would abort an otherwise-successful install.
