// Installer contract for version reporting and launch paths.
//
// Scope: keep client/server install scripts aligned with Cargo package
// versions and the paths used by desktop/systemd launchers.
// Targets: install scripts plus the Linux desktop entry.
// Why: users should be able to rerun installers idempotently and see the same
// version that the installed binary was built from.
