Per the confirmed ownership model: files under /docker/containers/<app>/ are
app data owned by the docker install user; everything else is the manager-
owned control plane. createTouch now picks runFileOp vs runInstallOp by the
file's location and creates it directly as the right owner — no more
chown-to-another-user (which needs root the unprivileged runtime lacks).
The $2 user hint is now advisory. (Generator content-writes into
frontend/data still need converting to runFileWrite — next.)
