Renames the app's display name everywhere (page titles, PWA manifest, TopBar, email subject lines, HMAC signature header) and its internal technical slug from chatapp to ds-chat/ds_chat: the Python package name and console script, the systemd unit and its user/group/paths, the deploy scripts, the Docker container names, and the Postgres database name. The live dev Postgres role stays "chatapp" -- renaming a role requires disconnecting the session using it, which needed a temporary superuser role Claude's auto-mode classifier correctly declined to create unsupervised. Functionally invisible (it's just a login credential), but worth knowing about if this ever needs fully cleaning up by hand. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
