The server's version is stamped like the app's (APP_VERSION) when packaged,
so it can compare against the manifest; --upgrade swaps the whole install
folder (app and server) and asks for a restart. update.sh/.bat no longer
need GTK.

- Strip the tarball's top-level folder; stage inside the install root
(same filesystem) and swap with full rollback; keep file modes.
- Semver prerelease ordering (1.2.3-rc1 < 1.2.3).
- UpdateController: background check, download with progress, apply,
restart; required-update wording for newer protocols; Check now.
- update.sh/update.bat in the bundle; Windows apply path (untested).
