# Move a web application's staged source directory into its new container's
# directory (as `webapp/`). Invoked by
# ea_podman::util::_ensure_latest_container() when an arbitrary-image install
# passes --webapp-dir — the install-time analog of an EA4 container package's
# ea-podman-local-dir-setup hook. The staged directory — the application's
# source itself — becomes `webapp/`, so nothing is left behind at the staged
# location and `webapp/` is the application's source root; everything beside
# it in the container directory belongs to the system, not the application.
